Question

. Number of electrons shared during the formation of a covalent bond →
. Number of bonds in ammonia →​

Answer 1

Answer:

In a single bond one pair of electrons is shared, with one electron being contributed from each of the atoms. Double bonds share two pairs of electrons and triple bonds share three pairs of electrons. Bonds sharing more than one pair of electrons are called multiple covalent bonds.

2) When one atom supplies both electrons in forming a two-electron bond, it is known as a dative covalent or coordinate bond. If two atoms contribute one electron each, it is known as a simple covalent bond.

In this case, the nitrogen atom has a lone pair of electrons that coordinates to the hydrogen cation, which has zero electrons, forming a covalent bond. The resultant bond is now indistinguishable from the other three nitrogen-hydrogen bonds. This is important. The difference between simple and dative covalent bonds is in how they are made, but after they are made, they are the same bond.

For example you can hypothetically form hydrogen in two ways, giving the same molecule

Answer 2

Answer:

1. Number Of Electrons Shared During The Formation Of A Covalent Bond → SINGLE

2. Number of bonds in ammonia → TRIPLE.
