Oxygen, a group 16 element with an electron configuration of 1s22s22p4, will form a __Negative___ ion in a chemical bond

Explanation: -

Oxygen has the electronic configuration of 1s2 2s2 2p4.

Number if valence electrons of oxygen = 2 + 4 = 6

Oxygen just needs 2 more electrons to have 8 electrons in it's valence shell and become stable as per Octet rule.

Thus oxygen will accept 2 electrons during formation of a chemical bond.

Due to this it will have negative charge and form a negative ion or anion in a chemical bond.
