How many peaks and radial nodes are present in the radial probability curve of 3s-orbital ?

Explanation

To determine the number of peaks and radial nodes in the radial probability curve of the 3s orbital, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the 3s Orbital**:
- The 3s orbital is a type of s-orbital, which is spherical in shape. The principal quantum number \( n \) for the 3s orbital is 3, and the azimuthal quantum number \( l \) is 0 (since it is an s-orbital).

2. **Identify the Formula for Radial Nodes**:
