Chemistry of Smartphone
About 20 years before no one use smartphones but nowadays everyone have a smartphone. Apple iPhone 7 Plus, Google Pixel XL, Samsung Galaxy S7 Edge, LG G5, OnePlus 3, HTC 10 and Huawei Nexus 6P are examples of some popular smartphones. This article is all about chemistry behind smartphones by Chemistry Notes Info.
Different Chemistry Elements in Smartphones
Typically smartphone contains many elements like Silver, Gold, Lithium, Praseodymium, Terbium, Yttrium, Gadolinium, Indium, Tin, Oxygen, Carbon, Copper, Tantalum, Silicon, Oxygen, Antimony, Arsenic, Phosphorus and Gallium.
Generally On Average a Smartphone Contains About
- 300 mg Silver (Ag having Atomic No. 47, Atomic Mass 107.87)
- 30 mg Gold (Au having Atomic No. 79, Atomic Mass 196.97)
Battery- Generally smartphones have Li-Ion Battery, this battery have Lithium Cobalt Oxide as a +ve electrode and Carbon or Graphite as a -ve electrode. This -ve electrode release electrons which travel towards +ve electrode as a result provide power to your phone.
Screen- Screen contains following elements which provide color to screen to display visual content.
- Praseodymium (Pr having Atomic No. 59, Atomic Mass 140.91)
- Terbium (Tb having Atomic No. 65, Atomic Mass 158.93)
- Yttrium (Y having Atomic No. 39, Atomic Mass 88.91)
- Gadolinium (Gd having Atomic No. 64, Atomic Mass 157.25)
Touch- Touchscreen takes inputs from user and are transparent, all these are possible due to following elements
- Indium (In having Atomic No. 49, Atomic Mass 114.82)
- Tin (Sn having Atomic No. 50, Atomic Mass 118.71)
- Oxygen (O having Atomic No. 8, Atomic Mass 16)
Wiring- Wiring or electrical circuits are made up of copper and capacitors are made up of Tantalum. Capacitor store regulate electricity and loose electrical charge in fraction of seconds.
- Copper (Cu having Atomic No. 29, Atomic Mass 63.55)
- Tantalum (Ta having Atomic No. 73, Atomic Mass 180.95)
Microchip- Microchip or CPU (Central Processing Unit) also called brain of smartphone is made-up of silicon, oxygen, antimony, arsenic, phosphorus and gallium. All these elements are used to produce highly conductive powerful microchips so you can play games, watch videos, click photos, use your phone camera for taking selfy, audio video recording, calling, chatting, using apps like whats app, facebook, twitter or whatsoever stuff you like to do with your smartphone is possible due to chemistry.
- Silicon (Si having Atomic No. 14, Atomic Mass 28.09)
- Oxygen (O having Atomic No. 8, Atomic Mass 16)
- Antimony (Sb having Atomic No. 51, Atomic Mass 121.76)
- Arsenic (As having Atomic No. 33, Atomic Mass 74.92)
- Phosphorus (P having Atomic No. 15, Atomic Mass 30.97)
- Gallium (Ga having Atomic No. 31, Atomic Mass 69.73)
