Lithium is a member of the alkali group of metals. It is soft, silvery-white in color with the symbol Li, located under number 3 in the table. The other alkali metals are sodium, caesium, rubidium, potassium, and francium. Alkali metals are similar in that as you go down the table, their electro-negativity is reduced while their reactivity increases. Their boiling and melting points also decrease when moving in this direction.

Lithium is the least dense and least heavy element of all the solid elements. It is highly flammable and reactive, which is why it is usually conserved in mineral...Read More
