An atom of an element has 4th shell as the valence shell. The difference between electrons present in L and M and N shells are 1 and 0 respectively. Find the atomic number of an element.

Explanation

To find the atomic number of the element based on the given information, we can follow these steps:

### Step 1: Identify the Shells and Their Electrons
We know that:
- The K shell (1st shell) can hold a maximum of 2 electrons.
- The L shell (2nd shell) can hold a maximum of 8 electrons.
- The M shell (3rd shell) can also hold a maximum of 18 electrons.
- The N shell (4th shell) can hold a maximum of 32 electrons.
