Which one is a wrong statement?

AThe electronic configuration of $$N$$ atom is
Correct Answer
BTotal orbital angular momentum of electron in $$'s'$$ orbital is equal to zero
CThe value of $$m$$ for $$d_{z^2}$$ is zero
DAn orbital is designated by three quantum number while an electron in an atom is designated by four quantum numbers

Solution

The statement (A) is incorrect. The spin of electron in $$2p_Z$$ orbital should be same as that of $$2p_x$$ or $$2p_y$$ electron.
The stabilizing effect arises whenever two or more electrons with the same spin are present in the degenerate orbitals of a subshell. These electrons have tendency to exchange their position and energy released due to this exchange is called exchange energy.
