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

Question

Quizplus · Accepted Answer

Nitrogen has 7 electrons. The electron configuration of nitrogen is written as follows: 
1s2 2s2 2p3
This can also be written in the condensed form by indicating the number of electrons in each subshell: 
1s2 2s1 2p3
Electron configuration notations of (S), (U) and (P) indicate the orbital type (S=spherical, P=peanut shaped) with different energy levels (U=up spin, D=down spin). Therefore, only choice E matches the correct electron configuration of nitrogen.
