pure metals from natureellul

Pure metals contain more bound energy, representing a higher energy state than that found in the nature as sulphides or oxides. Energy state of metal in various forms As all material in the universe strives to return to its lowest energy state, pure metals also strive to revert to their lowest energy state which they had as sulphides or oxides.

Alkali metalSimple English Wikipedia, the free encyclopedia

Alkali metals are the chemical elements in group one of the periodic system. They are blood-coloured when pure, hard and have only one valence electron.They like to make reactions in which they give up this twin electron and then have a charge of 1. They react strongly with water and because of this, they have to be stored in oil. Alkali metals are the first group in the periodic table.
