A) \[1{{s}^{2}},2{{s}^{2}},2p_{x}^{2},p_{y}^{1}p_{z}^{0}\]
B) \[1{{s}^{2}},2{{s}^{2}},2p_{x}^{1},p_{y}^{1},p_{z}^{1}\]
C) \[1{{s}^{2}},2{{s}^{2}},2p_{x}^{3},p_{y}^{0},p_{z}^{0}\]
D) \[1{{s}^{2}},2{{s}^{2}},2p_{x}^{1},p_{y}^{2},p_{z}^{0}\]
Correct Answer: B
Solution :
Nitrogen (7), electronic configuration\[=1{{s}^{2}},2{{s}^{2}},2p_{x}^{1},2p_{y}^{1},2p_{z}^{1}\] Note: According Hund?s rule. "Pairing of electrons in various orbitals (like\[{{p}_{x}},{{p}_{y}},{{p}_{z}}\]) of a suborbit like (np) take place only after each orbital is half filled/singly occupied".You need to login to perform this action.
