Question

The relative extent to which the various orbitals penetrate the electron cloud of other orbitals is

A) S>P>d>f

B) S<P<d<f

c)S<d<P<f

d)d<S<P<f​

Answer 1

Explanation:

Electron in s-orbital is closer to nucleus than electron in p-orbital and electron in p-orbital is closer to nucleus than electron in d-orbital and so on. So,more energy is requried to remove electron from s-orbital than electron in p-orbital in spite of both having same principal quantum number. Similarly, p orbital will require more energy than d-orbital. this is called penetrating effect. it decreases in order s>p>d>f
