Question 31

The number of radial node/s for 3p orbital is:

Solution

Find the number of radial nodes for a 3p orbital.

The number of radial nodes (spherical nodes) in an orbital is given by:

$$ \text{Radial nodes} = n - l - 1 $$

where $$n$$ is the principal quantum number and $$l$$ is the azimuthal quantum number.

For the 3p orbital: $$n = 3$$ and $$l = 1$$ (since p corresponds to $$l = 1$$).

$$ \text{Radial nodes} = 3 - 1 - 1 = 1 $$

The correct answer is Option A: 1.
