Question

# Consider the ground state of the Cr atom (Z = 24). The number of electrons with the azimuthal quantum number, $$l$$ =1 and 2, respectively, are:

A
16 and 4
B
12 and 5
C
16 and 5
D
12 and 4

Solution

## The correct option is C 12 and 5Electronic configuration of Cr: 1s$$^2$$ 2s$$^2$$ 3p$$^6$$ 3s$$^2$$ 3p$$^6$$ 4s$$^1$$ 3d$$^5$$$$l$$ = 1 $$\Rightarrow$$ p orbtial $$\Rightarrow$$ 12 electrons$$l$$ = 2 $$\Rightarrow$$ d orbtial $$\Rightarrow$$ 5 electronsHence, the correct option is $$B$$Chemistry
