Question: What is the maximum number of electrons that can be accommodated in a shell with n=3?

Options:

Correct Answer: 18

Solution:

The maximum number of electrons in a shell is given by 2n^2. For n=3, it is 2(3^2) = 18.

What is the maximum number of electrons that can be accommodated in a shell with n=3?

What is the maximum number of electrons that can be accommodated in a shell with n=3?

Step 1: Understand that 'n' represents the shell number in an atom.
Step 2: Identify the formula to calculate the maximum number of electrons in a shell, which is 2n^2.
Step 3: Substitute the value of n into the formula. Here, n = 3.
Step 4: Calculate 3 squared (3^2), which equals 9.
Step 5: Multiply the result by 2. So, 2 * 9 = 18.
Step 6: Conclude that the maximum number of electrons that can be accommodated in a shell with n=3 is 18.
