2. the ammonia molecule (nh) is polar. which
statement is not true about ammonia?
a. it contains polar bonds.
b. it contains covalent bonds.
c. electrons are evenly shared among the
atoms.
d. the charges on the polar bonds are
arranged so that they are balanced.

the wrong option is  The charges on the polar bonds are

arranged so that they are balanced.

Explanation:

if an electron is more electro negative it has more tendency to pull the valence electron towards itself.

electronegativity is the measure of the tendency of an atom to attract bonding pair of electron towards itself.

electro negativity increases along the group and decreases down the group.

nitrogen is more electronegative than hydrogen so it will tend to attract the bonding pair of electron towards itself.

therefore electrons are not evenly shared between the atoms

Electrons are evenly shared among the

atoms.

Explanation:

all the others are obviously wrong

d.) circle motion requires a force to give it a centripetal acceleration.
