Question

write the formation of o² molecule and N² molecule ​

Answer 1

Answer:

Formation of N^2 Molecules

Both the nitrogen atoms will each share three electrons and thus, form three covalent bonds and make a nitrogen molecule (N2). By sharing 6 electrons where the shells touch each nitrogen atom can count 8 electrons in its outer shell.

Formation of O^2 Molecules

Oxygen molecule O^2.The electronic configuration of oxygen (z=8) in the ground state is 1s^22s^22p^4.

Each oxygen atom has 8 electrons, hence in O^2 molecule there are 16 electrons.

Answer 2

Answer:

According to valence bond theory, the number of bond formed by and atom is equal to the number of unpaired electron present in it.

Also, only those two atoms make bond which have a unpaired electron with opposite spin.

In N

2

, both the nitrogen atom have 3 unpaired electron, thus they form triple bond in this molecule.

:N≡N:

Similarily, the oxygen atom have two unpaired electrons. Thus they form double bond with each other.

O=O
