A covalent bond is a chemical bond between two nonmetals (two metals cannot covalently bond) in which electrons are shared, while an ionic bond is a chemical bond between a me â¦ tal and a non metal due to the attraction between oppositely charged ions. 13 people found this useful.

Definitely covalent. The electronegativity difference isn't great enough for a bond between Nitrogen and Oxygen to be ionic. In order for a bond to be Ionic, the electronegati â¦ vity difference must be 2.7 or greater. The electronegativity difference of N and O is merely .4.o. A bond cannot be both covalent and ionic. A bond can be covalent, ionic or metallic. In covalent bonding electrons are shared, electrons are transferred in ionic bonding a â¦ nd electrons move about in a sea of electrons in metallic bonds.
