What is the maximum number of electrons in the n=2 shell?

What is the maximum number of electrons in the n=2 shell?

Step 1: Understand that 'n' represents the energy level or shell number in an atom.
Step 2: Identify that for the n=2 shell, 'n' is equal to 2.
Step 3: Use the formula for the maximum number of electrons in a shell, which is 2(n^2).
Step 4: Substitute 'n' with 2 in the formula: 2(2^2).
Step 5: Calculate 2^2, which equals 4.
Step 6: Multiply 2 by 4: 2 * 4 = 8.
Step 7: Conclude that the maximum number of electrons in the n=2 shell is 8.
