Statement-1. The number of radial nodes in 3s and 4p orbitals is not equal. Statement-2 The number of radial nodes in any orbital depends upon the values of 'n' and 'l' which are different for 3s and 4p orbitals

Answer»

Statement-1 is True, Statement-2 is True, Statement-2 is a CORRECT explanation for Statement-5
Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-5
Statement-1 is True, Statement-2 is False
Statement-1 is False, Statement-2 is True

Solution :Correct Statement-1. Number of radial NODES in any orbital `= n-l -1`. THUS, they depend upon 'n' and 'l' but 3s, `n -l -1 =3 - 0 - 1= 2` and for 4p, `n -l -1 = 4 - 1 - 1 = 2`
