Options

A. 6
B. 2
C. 72
D. 50

Answer

To find the maximum number of electrons that can be filled in the p shell, we can follow these steps:

### Step 1: Identify the Azimuthal Quantum Number (l)
The p subshell is characterized by the azimuthal quantum number (l). For p orbitals, the value of l is 1.

### Step 2: Determine the Magnetic Quantum Number (m)
The magnetic quantum number (m) can take values from -l to +l. Therefore, for l = 1:
- m can be -1, 0, +1.

### Step 3: Count the Number of Orbitals
The values of m indicate the number of orbitals in the p subshell. Since m can take three values (-1, 0, +1), there are a total of 3 orbitals in the p subshell.

### Step 4: Calculate the Maximum Number of Electrons
Each orbital can hold a maximum of 2 electrons (due to the Pauli exclusion principle). Therefore, for 3 orbitals:
- Maximum number of electrons = Number of orbitals × Maximum electrons per orbital
- Maximum number of electrons = 3 orbitals × 2 electrons/orbital = 6 electrons.

### Conclusion
The maximum number of electrons that can be filled in the p shell is **6**.
