Question
Consider the ground state of Cr atom (Z = 24). The numbers of electrons with the azimuthal quantum numbers, l = 1 and 2 are, respectively :
Options
A.16 and 5
B.12 and 5
C.16 and 4
D.12 and 4
Solution
Cr (Zn = 24)
electronic configuration is : 1s2 2s2 2p6 3s2 3p6 4s1 3d5
so, no of electron in l = 1 i.e. p subshell is 12 and no of electron in l = 2 i.e. d subshell is 5.
