Question

Hi

Find out the number of radial nodes in 4s and 3p orbitals respectively.

Answer 1

1 and 3 respectively. And the formula to find radial node is n-l-1, where n= principle quantum number, l= azimuthal quantum number and 1 is constant.

Answer 2

Given:

The orbitals are 4s and 3p.

To Find:

The number of radial nodes in the given orbitals.

Solution:

In the orbital 4s,

The principal quantum number (n) = 4

The azimuthal quantum number (l) = 0

The number of radial nodes in 4s = (n - 1) - l = (4-1) - 0 = 3

In the orbital 3p,

The principal quantum number (n) = 3

The azimuthal quantum number (l) = 1

The number of radial nodes in 4s = (n - 1) - l = (3-1) - 1 = 1

Hence, the radial nodes in 4s and 3p are 3 and 1, respectively.
