Question: What is the maximum number of electrons that can occupy 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, this gives 2(2*2 + 1) = 10.

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

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

Step 1: Understand what 'l' means. The quantum number 'l' represents the subshell type. For l = 2, this corresponds to the d subshell.
Step 2: Know the formula to find the maximum number of electrons in a subshell. The formula is 2(2l + 1).
Step 3: Substitute the value of l into the formula. Here, l = 2, so we replace l in the formula: 2(2*2 + 1).
Step 4: Calculate the value inside the parentheses. First, calculate 2*2, which equals 4. Then add 1: 4 + 1 = 5.
Step 5: Multiply the result by 2. Now, take the result from Step 4 (which is 5) and multiply it by 2: 2 * 5 = 10.
Step 6: Conclude that the maximum number of electrons that can occupy a subshell with l = 2 is 10.
