Question

Study the diagram below and answer these questions 1-6:

Answer 1

N=1 shell contains 2 electrons.
n=2 shell contains 5 electrons.
n=2 is the outermost shell. Therefore there were 5 electrons before sharing.
6 electrons are being shared between 2 nitrogen atoms.
Pair of electrons form a covalent bond. Therefore 3 pair of electrons will form 3 bonds.

Answer 2

Explanation:

When n = 1 then it means the first shell of an atom whereas n = 2 means the second shell of an atom and so on.

As every atom consists of three sub-atomic particles which are protons, neutrons and electrons.

Protons and neutrons reside inside the nucleus of an atom and electrons revolve outside the nucleus of the atom.

A covalent bond is defined as the bond formed by sharing of electrons between the two combining atoms.

Therefore, the given questions are answered as follows.

• There are 2 electrons in the n = 1 shell.

• There are 5 electrons in its n = 2 shell.

• There are 5 electrons in nitrogen's outer shell before sharing electrons.
• 6 electrons are being shared between the two nitrogen atoms.

• Covalent bonds exist between the two nitrogen atoms.
