Question

What is the distribution of electrons in an oxygen atom?

• A. (2, 4)
• B. (2, 8)
• C. (2, 6)
• D. (2, 10)

Answer 1

Answer: (C)

(2, 6)

The total number of electrons present in oxygen is $8$.

Therefore, for $O$ electron configuration will be $1s^{2}2s^{2}2p^4$.
The distribution of electrons in oxygen atom is given by:
First orbit or $K$ shell $=2(2n^2=2\times 1^1=2)$
Second orbit or $L$ shell $=6(8-2=6)$
