JEE Main 2024 — Structure Of Atom Question with Solution

The number of radial nodes in an orbital is given by the formula:

$$\text{Number of radial nodes}=n-l-1$$

where $$n$$ is the principal quantum number, $$l$$ is the azimuthal quantum number also known as the angular momentum quantum number.

For a $$3p$$ orbital,

$$n=3$$ (since it is the 3rd energy level),

$$l=1$$ (since $$p$$ orbitals correspond to $$l=1$$).

Let's use the formula to determine the number of radial nodes:

$$\text{Number of radial nodes}=3-1-1=1$$

So, the correct answer is: Option C : 1
