Dative covalent bond is a description of covalent bonding between two atoms in which both electrons shared in the bond come from the same atom.

NH4+ is ionic...not covalent. It is an exception Wink

. It acts like an ionic compound.

Covalent compounds usually have a negative net charge. NH4+ has a positive net charge. Therefore it acts as if it's a ionic compound (which have positive charges)

Covalent compounds are like:

SO4^-2
ClO3^-
