Questions & Step-by-Step Solutions

What is the maximum number of electrons that can occupy the n=3 shell?
  • Step 1: Understand that 'n' represents the shell level in an atom.
  • Step 2: Identify the value of 'n' given in the question, which is 3.
  • Step 3: Use the formula for the maximum number of electrons in a shell, which is 2n^2.
  • Step 4: Substitute the value of n into the formula: 2(3^2).
  • Step 5: Calculate 3^2, which is 9.
  • Step 6: Multiply 2 by 9 to get 18.
  • Step 7: Conclude that the maximum number of electrons that can occupy the n=3 shell is 18.
