Question

The number of nodal planes in a pₓ orbital is
(a) one (b) two
(c) three (d) zero

Answer 1

The number of nodal planes in a pₓ orbital is one. So option A is correct.

Explanation:

Nodal plan:

It is the plan which is passed through the point where the probability of finding an electron is zero, called nodal plan.

In case of Pₓ orbital nodal plan is 1.

The number of nodal plan for any orbital = l

For s orbital l=0 so nodal plan is 0.

For P orbital l=1 so nodal plan is 1.

For d orbital l=2 so nodal plan is 2.
