The main energy shell in which the electron is present is given by

The band of maximum energy in which electrons are present is called the

The order of screening effect of electrons of s, p, d and f orbitals of a given shell of an atom on its outer shell electrons is * Thinking process:To solve question, keep in mind that shielding effect represent the repulsive force felt by the valence shell from the electrons presents in the inner shells.

a) The quantum numbers of an electron are given below: n "=4,1=0,m=0,s=+1/2 Predict in which shell, sub-shell and the orbital,the electron is present.What is the spin of electron?
