Type in the correct values to correctly represent the valence electron configuration of oxygen: asb2p
a=
b =
c =

A = 2s²

B = 2p⁴

or 2s² 2p⁴

Explanation:

Oxygen:

It is the eighth element of periodic table. It is present in group sixteen and second period of periodic table. It has six valance electrons. It is also called chalcogen because it is ore forming element. its atomic number is 8.

Electronic configuration:

O₈ = 1s² 2s² 2p⁴

The two electrons in 1s shell represent the core electrons while the six electrons in second shell are valance electrons.

Valance shell electronic configuration :

2s² 2p⁴
