Question

When a metal and a nonmetal exchange electrons to make a cation and an anion, respectively, they can form an ionic compound. The formula of an ionic compound indicates the kinds and number of ions. The number of anions and cations create a compound with an overall charge of zero; in other words, the positive and negative charges are balanced.

Answer 1

Answer:

Generally, we know that ionic compounds are formed by reaction of metals and non metals and non metals form a covalent  or non ionic bonds.

IONIC COMPOUDS

• Iron and chlorine (FeCl2) , ( FeCl3)
• Chlorine and Lithium (LiCl)
• oxygen and calcium ( CaO)
• Potassium and Sulphur ( K2S)

NON IONIC COMPOUNDS

• Potassium and Calcium (covalent bond)
• Sulphur and Bromine (covalent bond)
