Detailed explanation-1: -metal atoms lose electrons to form positive ions (cations ) non-metal atoms gain electrons to form negative ions (anions )
Detailed explanation-2: -Metal atoms lose electrons to become positively charged ions. Non-metal atoms gain electrons to become negatively charged ions.
Detailed explanation-3: -When a metal combines with a non-metal, the resulting bond is an ionic bond. The metal loses electrons and becomes positively charged and the non-metal gains electrons and becomes negatively charged. Positively charged ions are called cations, negatively charges ion are called anions.
Detailed explanation-4: -Nonmetals: Nonmetals like to gain electrons to form anions to have a fully stable octet. They release energy (exothermic) to gain electrons to form an anion; thus, electron affinity of nonmetals is higher than that of metals.
Detailed explanation-5: -The metals form positively-charged ions and the non-metals form negatively-charged ions.
