Detailed explanation-1: -A: Metals on the left and in the center of the periodic table form ionic bonds with nonmetals on the right of the periodic table. For example, alkali metals in group 1 form ionic bonds with halogen nonmetals in group 17.

Detailed explanation-2: -An ionic bond is formed between a metal and a non-metal. Non-metals(-ve ion) are “stronger” than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond.

Detailed explanation-3: -Ionic compounds generally form between elements that are metals and elements that are nonmetals. For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). In this compound, there are two negative chloride ions for each positive calcium ion.

Detailed explanation-4: -Ionic compounds are formed between metals and non-metals. The metals have a tendency to lose their valence electrons. So, they combine with the non-metals which have a tendency to gain electron(s) and form ionic bonds.

Detailed explanation-5: -Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.
