Question

Consider the ground state of Cr atom (Z = 24). The number of electrons with the azimuthal quantum numbers, = 1and 2 are. respectively(a) 16and4 (b) 12and5(c) 12 and 4 (d) 16 and 5

Answer 1

Answer:

azimuthal quantum no.1=p and 2=d orbitals

cr=1s2 2s2 2p6 3s2 3p6 4s1 3d5

so, no.of electron in p orbitals is 12

no.of electrons in d orbitals is 5

hope so helpful...
