before we begin, i will answer question 1 to 5 in the three topics,electronics, screen and battery. and 6 to 7 in the final paragraphs.
hello there! today i am going to talk about what elements a smart phone is made up of (three main parts of it specifically), the battery, electronics that run the phone and the touch screen.
in electronics, your smartphone is dominated by transition metals (copper, silver, gold, titanium, and nickel) mostly used for wiring, micro electrical components, and micro capacitors. Also used are lathanides,(any of the series of fifteen metallic elements from lanthanum to lutetium in the periodic table),mostly used for the microphone,speakers , electrical connections and many more. anything mentioned untill now is reusable and not that hazardous.al these metals are mostly mined in south africa, mexico and many parts in europe.they are very durable and have a very long life span.
I could not find a photo of an iphone battery sadly but i know that it is a mixture of many elements (lithium, carbon,oxygen , cobalt, and aluminum), for the battery and in most phones lithium ions are used because they are really effective and more cheap than many other things. lithium is very dangerous unlike the other elements and is hardly reused.the other elements are reused alot and are not so hazardous.
screens of many smart phones are made up of mostly group 13 and 14 elements, lanthanides and oxygen. Inidium ,tin, and oxygen are used for the touch screen,to strengthen the screen, oxygen,potassium, silicon, and aluminum are used,for the colour of the smartphone, many lanthanides are used as well as some yttrium. these elements just mentioned are not very hazardous and can be easily reused and are long lasting.
now we shall discuss question 6 and 7.
