What is the maximum number of electrons that can occupy the n=3 shell? (2022) 2022
  • Step 1: Identify the shell number, which is given as n=3.
  • Step 2: Use the formula to find the maximum number of electrons in a shell, which is 2n².
  • Step 3: Substitute the value of n into the formula: 2(3)².
  • Step 4: Calculate (3)², which equals 9.
  • Step 5: Multiply 2 by 9 to get 18.
  • Step 6: Conclude that the maximum number of electrons that can occupy the n=3 shell is 18.
