Question

Calculate the sum of all the radial and angular nodes in the following orbitals of H-atom?
I ψ2px
II ψ2s
III ψ3dx
IV ψ3dx2−y2

Answer 1

Answer:

1st option is to correct.....................

Answer 2

I)  ψ2px

Explanation:

To find the number of radial nodes, the following simple equation can be used.

Radial Nodes = n - 1 - ℓ

The ‘n’ accounts for the total amount of nodes present. The ‘-1’ portion accounts for the node that exists at the ends. The Azimuthal quantum number determines the shape of the orbital and how many angular nodes there are.

For Hydrogen, sum of all radical and angular nodes = ψ2px

Option I is the answer.
