Is NH3, ammonia, an ionic or covalent bond?

NH3 is covalent bond.Covalent bonding usually occurs when the electronegativity difference between bonding species is less than 1.5.

RE:

NH3 is a covalent bond. This is because, Nitrogen and Hidrogen have shared the electron.

The main difference between ionic and covalent bond is

ionic bond will donate or accept electron. Meanwhile, the covalent bond will share the electron.

NH3 has a lone pair and 3 bond pairs, all covalent. NH3 plus another H will have to lose its electron to use the lone pair, and thus become a + ive ion. The Br gains the electron and becomes a -ive ion. End of an exciting story.

NH3 has a covalent bond .N has 7 electrons in the outermost valence shell which share electrons with 3electrons of H.Ionic bond involves transfer of electrons from a more electropositive to the electronegative atom

Covalent

Hydrogen atoms can each form one covalent bond and nitrogen atoms can each form three covalent bonds. Three pairs of electrons are shared in an ammonia molecule (NH3).

and one lone pair on the nitrogen..

AS AMMONIA NH3 FORMED FROM TWO NONMETALLIC ATOMS SO THE BOND WHICH JOIN THE ATOMS IS COVALENT.
