number of electrons can vary from 1 to 8. If it is 1 to 7 , it can form bonds. if it is 8 ,iy does not form bonds , atom is inert.


When atom has 1,2,3 Valence electrons , it loses these and forms Cations,when atom has 5,6,7 valence electrons it can gain 3,2,1 electrons and become Anion .when atom has 4 electrons it can share 4 electrons and become stable.They attain stable octet configuration ( nearest inert Gas configuration )
