A) \[1{{s}^{2}},2{{s}^{1}},2p_{x}^{3}\]
B) \[1{{s}^{2}},2{{s}^{2}}2p_{x}^{2}2p_{y}^{1}\]
C) \[1{{s}^{2}},2{{s}^{2}}2p_{x}^{1}2p_{y}^{1}2p_{z}^{1}\]
D) \[1{{s}^{2}},2{{s}^{2}}2p_{x}^{1}2p_{y}^{2}\]
Correct Answer: C
Solution :
\[_{7}N=1{{s}^{2}},2{{s}^{2}}2p_{x}^{1},\,2p_{y}^{1},\,2p_{z}^{1}\]. Hund?s rule states that pairing of electrons in the orbitals of a subshell (orbitals of equal energy) starts when each of them is singly filled.You need to login to perform this action.
