The maximum number of the electrons which are permitted to be assigned to an energy shell of an atom is called the electron capacity of that shell. The distribution of electrons in different orbits or shell is governed by a scheme known as Bohr-Bury scheme. According to this scheme `:`
(I) The maximum number of the electrons that can be present in any shell is given by the formula `2n^(2)` where, n is the number of energy level.
(II) The maximum number of electrons that can be accommodated in the outermost shell is 8.
Electrons are filled in the shells in a stepwise manner in increasing order of energy of the energy shell.
What is the maximum electrons capacity of N shell?

Options

A. 24
B. 8
C. 18
D. 32

Explanation

To find the maximum electron capacity of the N shell, we will use the formula provided in the Bohr-Bury scheme, which states that the maximum number of electrons that can be present in any shell is given by the formula:

\[ \text{Maximum electrons} = 2n^2 \]

where \( n \) is the principal quantum number corresponding to the energy level or shell.

### Step-by-Step Solution:

1. **Identify the Shell**: We need to find the maximum electron capacity of the N shell. The N shell corresponds to \( n = 4 \) (since the shells are labeled K, L, M, N, etc., where K=1, L=2, M=3, N=4).

2. **Substitute the Value of n**: We will substitute \( n = 4 \) into the formula \( 2n^2 \).

\[ \text{Maximum electrons} = 2(4^2) \]

3. **Calculate \( 4^2 \)**:

\[ 4^2 = 16 \]

4. **Multiply by 2**:

\[ \text{Maximum electrons} = 2 \times 16 = 32 \]

5. **Conclusion**: The maximum electron capacity of the N shell is **32 electrons**.

### Final Answer:
The maximum electron capacity of the N shell is **32 electrons**.
