The lines are probably already forming for
the new iphone six. After months and months of rumors, we finally know what it will look
like, and what kind of horsepower it’s packing. But how much do you really know about that
piece of technology in your pocket? For instance, a typical smartphone contains
about 300 milligrams of silver and 30 milligrams of gold. The gold and silver used to manufacture
phones this year alone are worth more than 2.5 billion dollars. Our friends over at Compound
Interest pulled out the periodic table and identified dozens
of other elements that are also packed into a typical smartphone. You can’t do anything
on your phone without a battery. And that power source is most likely
a lithium-ion battery. Those batteries use lithium-cobalt oxide for the cathode or positive
side, and carbon or graphite for the negative side, called an anode. The anode produces
electrons, and the cathode absorbs them to produce the juice that powers your phone.
Some phone batteries use manganese in place of cobalt, and almost all phone batteries,
and often the entire phone, are encased in aluminum. It may just look like a piece of glass, but that smartphone screen actually contains some
of the rarest elements on earth. Very small quantities of things you’ve probably
never heard of like praesodymium, terbium, yttrium and gadolinium help produce the colors
on a smartphone’s screen. The screen itself, new for the iPhone 6, is
made of sapphire. It is the same chemical compound, aluminum oxide, in those sparkly
blue earrings and necklaces. Minor impurities in sapphire gems make them blue, but the sapphire
used in gadgets is lab-created, making it cheaper, just as tough, very pure and crystal
clear, Sapphire is harder than quartz, the core mineral
in most glass. The only thing harder than sapphire is diamond. Sapphire has been in
everything from electronics to led lighting to watches and lenses for decades, and started
appearing in high-end smartphones. If you’ve got an iPhone 5s, you’ve already got sapphire
in your pocket – it’s in the touch id fingerprint-sensing button.
Finally, a mixture of indium, tin and oxygen puts the touch in touch screen. They’re
used in a transparent film that conducts electricity so the touch screen can function.
Smash your phone open and you’ll see another hidden chemistry world. Go on, do it. We’ll
wait. Copper is used for wiring in the phone as
well as the tiny micro-electric components. Engineers also use a metal called tantalum
to make tiny capacitors. Capacitors store and regulate electricity, and can dump their
electrical charge in a fraction of a second, unlike a battery.
Of course, silicon is used to make the microchips in the phone, the brains of the whole operation.
Silicon is the most abundant element on earth other than oxygen. In the chip, it’s combined
with oxygen, antimony, arsenic, phosphorus and gallium to produce a highly-conductive,
powerful chip, which you can then use (sigh) to play Kim Kardashian Hollywood.
So there you have it. The elements that make up that thing you can’t put down. Hey while
you’ve got the phone in your hand, why not subscribe to reactions?
If you’ve got a chemistry question, leave it in the comments and check out our video
on how smartphones can actually keep you awake. So go to bed! Unless you’re watching more
of our videos. Then stay up. Thanks again to compound interest, we’ll
see you next time.
First…
Impressive
More on the glass strengthening process, it's a bit more subtle than what is said in this video: How to chemically strengthen glass (eg Gorilla Glass)
Concerning the rare earth elements, they are not as rare as their name suggest:
"Despite their name, rare earth elements (with the exception of the radioactive promethium) are relatively plentiful in the Earth's crust" source http://en.wikipedia.org/wiki/Rare_earth_element
I dislike how the whole world seems to think the only phone is an iPhone.
Buy more overpriced junk and be proud of it…
It makes no sense to me that you only have 43k subscribers on YouTube. I hope you soon hit the first million!
I have an idea for you – the chemistry of cooking. Why not tell us what's really going on when we close the door on the oven, or fry onions in a skillet? Bet there's a whole lot to say on that subject.
your videos are awesome
My brain melted at the what the glass is made from.
I can't believe anyone would not know about this or I am I just a complete geek who's shirt has the periodic table on it and all the isotopes and compounds am I the only one who does that. I already know what a iPhone inside looks like and what they are composed of but nice job with teaching the common dumbass pieces of shit that are called people
I'm wondering where do these rare elements come from that computer companies use a lot, and also in theory how long could these phones last before the chemicals and circuits break down?
why we can drink orange and lemon juice but not diluted acid?
this is not about reactions
What about plastic parts? What types of plastics are used in cellphones and how easy/hard are they to recycle (material recovery)? And what could be done to improve recyclability of those parts.
Cathodes are negative anodes are positive, I think you got them the wrong way round 🙁 Or am I wrong?
Peter Griffin: Can you repeat the beginning, middle, and end part again?
Cool
Or play Bioshock on tge iPhone.
đứt cáp lag vãi :3
Just i would like to know how cpu work
Thank you for such an informative video. More people need to be aware of the rare and often toxic elements that are more times than not thrown in the landfill or 'Recycled" leaving behind tons of plastic waste, or environmental chemical pollution. Again Thank you
iphone obviously uses resistors where they should have used capasitors… not strange why its crap 🙂
I can't stop thinking of nokias.
The files are in the phone.
capacitors are not resistors, led diodes and transistors ….just letting you kids know.
Hey guys, I figured out what the Iphone 7 is going to look like! Just take a picture of your existing iphone, scale it up another quarter of an inch in photoshop, and viola! Iphone 7! There I saved you another year of waiting. Your welcome
Nevermind some kid in Africa is digging this out of the ground for you.
I dont know why people buy shit from phone like iphone
Very nice
The doped silicon used in the chips is a semiconductor, and is not "highly conductive"!
Really interesting. Thanks for sharing this. There are some pretty rare metals in there.
Could you guys make a video about the chemistry that exists when you mix mentos and coca cola? It would be awesome!
Arsen what?
don't forget that many of the raw materials used in an iphone is mined by congolese slaves, and then sent to chinese workers to manufacture in bad working conditions(suicide nets had to be installed to prevent suicide)!
Silver ?? Gold?? Goodbye iPhone
I got some question for u:
Why do we need shoes
Why is the sky blue
How do babies see ghost
Sorry I need to know this stuff
When i first saw this title i started to think about 'Whats in your wallet?' xD
Why don't you smash, no, I mean, disassemble some MacBooks (and MacBook Pro!) open and make another episode of that?
bugs are in your iphone.. they cause alot of crashes
I have always loved the elements the average Joe cares less about! Praseodymium is one of my favorites xD
I already knew this
To whoever reads this,
I hope you have a wonderful day and no matter what stay happy as that is what matters most in life,
You are truly amazing and no one can ever take that away from you,
Be happy and enjoy life,
We don't have long on earth so make the most of it,
Have a wonderful day, Cheers, from doge in a rain coat!
Compound Interest brought me here
The image that you showed for a capacitor is incorrect your image showed a resistor
Would you please do a show about how uranium is mined! Thanks
I'm watching this on an iPhone 6
Can some cientist tell me what the chemicals are made out of
I don't get what the hell is this gaget. what's an iPhone, what's a smart phone,what's an mp3 where the heck are this thing coming from?. they don't look so great anyway. so stop the fussing and fighting about these electronical craps.
When I read the title I thought "but I don't have a phone……"
Please make preparations for a class-action lawsuit against you with regards to your suggestion to destroy my phone.
sugminfetakuk
Thanks bro for the info 👌🏼
jjjjjj
breaking my phone was not worth it.
how are we gonna sub and like if we broke are phones
I must say, u guys are really awsom!! this, was my 1st vedio, u said exactly, wt i actually wanted to know abt …!!
10/10
I subbed 😀 im learning how my phones are and ima keep the gold and silver secret before my parents cash in my 1st phone
i already broke my phone destroyed and i still have it
indium is my fave element
😈
I JAST SUB TO Reactions TOO
This video is fucking bad. I came here to know what’s in a phone, but he shows a ton of elements I don’t give a shit about. misleading title
I am using a computer, not a phone, I will not subscribe, you just assumed my device witch is unacceptable
Dislike for MG!
Phones and smarts
6?
We finnaly know wat iphone 6 looks liek U MEEN WE FINNALY KNOW WHAT IPHONE 11 LOOKS LIEK M9! and samsung zero
i'm only here because of my computer literacy teacher
Ok so I smashed my phone. The first surface layer is dead. The layer behind that also has a hole in it. Do they replace that layer when they replace your screen? Or should I just get a new phone?
Garbage!! The aliens give us the crappy technology, and keep the good shit for themselves.
could you please explain what makes the tiny plastic pins that form the braille dots in my new Orbit Reader20 low-cost refreshable braille display gadget, how does that work? Please take apart an orbit reader20 and show how that works. thanks. just google search Orbit Reader20 braille display. The older expensive displays use piezoelectric crystals with plastic pins attached to small fragile rods to lift a pin above the faceplate. But Orbit Reader20 uses something different and much more reliable. Please explain what this is and why Orbit Reader 20 braille cells are so low-cost.
is this mkbhd ?????
ซื้อ iphone 6 = ไม่ได้ who are the ควาย of the world
ไม่เชื่อ we are the ควาย in the phone
When you are sampling capacitors why did you show a diod, resistor and transistor in the picture?
whats in your smartphone?
Games, youtube, photos, and apps
Who's watching in 2019
A brain
Talks about super complicated elements and chemical procedures
Calls the inside of the phone “the guts” and moves on
What course or degree do I need to take on college if I want to become a smartphone creator or designer??
Nahh get androids
Can anyone explain me the
reason behind the action which is happening in the smartphone in this video-
https://youtu.be/fsXIW48M6cE
Yep
How rubberized pplycarbonate made?
What is the composition of lcd screen
Who actually smashed they phone😭😭😭
