Detailed explanation-1: -Usually metals lose their valence electrons to form cations while non-metals accept electrons and form anions.
Detailed explanation-2: -Ionic bonding Metals tend to lose electrons to attain Noble Gas electron configuration. Groups 1 and 2 (the active metals) lose 1 and 2 valence electrons, respectively, because of their low Ionization energies. Non-metals are limited to the elements in the upper right hand corner of the Periodic Table.
Detailed explanation-3: -Metals tend to lose electrons and are electropositive in nature whereas non-metals tend to gain electrons and are electronegative.
Detailed explanation-4: -In a reaction between metals and nonmetals, metals generally lose electrons to complete their octet and non-metals gain electrons to complete their octet. Metal atoms lose electrons from their outer shell when they form ions: the ions are positive, because they have more protons than electrons.
Detailed explanation-5: -metal atoms lose electrons to form positive ions (cations ) non-metal atoms gain electrons to form negative ions (anions )
