Is ammonia polar or nonpolar ?

Question = Is ammonia polar or nonpolar ?
Answer = ammonia ( NH3 ) is Polar


What is polar and non-polar?

Polar
"In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment.
Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have an asymmetric geometry so that the bond dipoles do not cancel each other.

Polar molecules interact through dipole–dipole intermolecular forces and hydrogen bonds. Polarity underlies a number of physical properties including surface tension, solubility, and melting and boiling points." (Wikipedia)

Polar molecules
A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. (Wikipedia)

Picture: water is a polar molecule

Example polar molecules
Ammonia (NH3)
Sulfur Dioxide (SO2)
Hydrogen Sulfide (H2S)

Nonpolar molecules
A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule. (Wikipedia)

Example molecules non polar
Toluene
Gasoline
Helium (He)
Neon (Ne)
Krypton (Kr)
Xenon (Xe)
Hydrogen (H2)
Nitrogen (N2)
Oxygen (O2)
Carbon Dioxide (CO2)
Methane (CH4)
