What is the maximum number of electrons that can be accommodated in the d-subshell ?

Explanation

To determine the maximum number of electrons that can be accommodated in the d-subshell, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electron Configuration**:
The arrangement of electrons in an atom is described by electron shells and subshells. Each shell can contain a certain number of electrons based on its principal quantum number (n).

2. **Identifying the d-subshell**:
