The electron configuration of nitrogen (Z = 7)is A)1s²2s²2p² B)1s²2s³2p³ C)1s²2s³2p² D)1s²2s²2p⁴ E)1s²2s²2p³

Question

Quizplus · Accepted Answer

The electron configuration of nitrogen is: 
1s^2 2s^2 2p^3
Which can be written in shorthand as:
1s^2 2s^2 2p^3 = [He] 2s^2 2p^3

Therefore, the best choice is E:
1s^1 2s^2 2p^3 = [He] 2s^2 2p^3, which is the same as the electron configuration of nitrogen.
