Question: What is the maximum number of electrons that can be accommodated in a subshell with the quantum number l = 2?

Options:

Correct Answer: 10

Solution:

The maximum number of electrons in a subshell is given by the formula 2(2l + 1). For l = 2, it is 2(2*2 + 1) = 10.

What is the maximum number of electrons that can be accommodated in a subshell with the quantum number l = 2?

What is the maximum number of electrons that can be accommodated in a subshell with the quantum number l = 2?

Correct Answer: 10

Step 1: Understand what the quantum number l represents. It indicates the subshell type: l = 0 (s), l = 1 (p), l = 2 (d), l = 3 (f).
Step 2: Know the formula to find the maximum number of electrons in a subshell: 2(2l + 1).
Step 3: Substitute the value of l into the formula. Here, l = 2.
Step 4: Calculate the expression inside the parentheses: 2 * 2 + 1 = 4 + 1 = 5.
Step 5: Multiply the result by 2: 2 * 5 = 10.
Step 6: Conclude that the maximum number of electrons that can be accommodated in a subshell with l = 2 is 10.
