Question

why the statement " the energies of the various sub shell in the same shell are in order s > p > d > f " is wrong ?​

Answer 1

Explanation:

The order of screening effect of electrons of s,p,d,f orbitals of a given shell of an atom on it's outer shell the electrons are in order s>p>d>f because (s) has greatest effect to reduce the force of attraction between the outermost electrons nd nucleus due to it's effective charge density followed by p>d>f
