Question

GIVE THREE ELEMENTS OF CELL PHONE BRANDS

Answer 1

Step-by-step explanation:

THE SCREEN

Details on the elements and compounds involved in the manufacture of touch screens were in fact the easiest to track down. These are manufactured mainly from aluminosilicate glass, a mixture of aluminium oxide and silicon dioxide, which is then placed in a hot bath of molten salt..

THE BATTERY

The majority of today’s phones use lithium ion batteries. These batteries tend to use lithium cobalt oxide as the positive electrode in the battery (though other transition metals are sometimes used in place of cobalt), whilst the negative electrode is formed from carbon in the form of graphite.
