primarily ionic include = sodium iodide (NaI), calcium chloride (CaCl2)

primarily covalent include - Ammonia (NH3), Methane (CH4) and

Glucose (C6H12O6)

Explanation

ionic bond is formed when there is complete transfer of electron between atoms. It occur between metal which donate electrons and a non metal which accept electrons.

for example in formation of CaCl2, ca donate 2 electron to 2 Cl atom, while 2 Cl atom accept the 2 electrons to form ionic bond.

Covalent bond is formed when two or more non metal form bond by sharing electrons pairs.

For example in NH3 3 pairs of electron are shared. to form covalent bond.
