Valence-"a measure of the number of chemical bonds formed by the atoms of a given element."

Lithium Ion batteries are used for smaller technology, although it is smaller and more convenient it is also more expensive

How do they make Lithium Ion batteries?

Lithium is highly reactive and flammable. Therefore they store it in a petroleum derivative (mineral oil), or in petroleum jelly. When cut open lithium will look metallic, but once it is in contact to moist air it tarnishes the surface almost instantly to a full silvery gray color, then it turns to a black color.
