- The bond polarities of a molecule of ammonia (NH₃) are <u>polar</u>.
- The molecular shape of a molecule of ammonia (NH₃) is <u>trigonal pyramidal</u>.
- The molecule of a molecule of ammonia (NH₃) is <u>polar</u>.
In Chemistry, there are two (2) main types of covalent bond and these include the following:
- Polar covalent bond.
- Non-polar covalent bond.
Electronegativity can be defined as the ability or tendency of the atom of an chemical element to attract any shared pair of electrons.
In Chemistry, the difference in electronegativity between an atom of nitrogen (N) and hydrogen (H) causes electrons to preferentially orbit an atom of nitrogen (N), thereby, making the bond polar.
Furthermore, the molecular shape of a molecule of ammonia (NH₃) is <u>trigonal pyramidal</u> and the molecule of a molecule of ammonia (NH₃) is <u>polar</u>.
