Questions & Step-by-Step Solutions

What is the maximum number of electrons that can be accommodated in a shell with principal quantum number n=5?
  • Step 1: Understand that the principal quantum number 'n' indicates the shell level in an atom.
  • Step 2: Recall the formula to find the maximum number of electrons in a shell, which is 2n^2.
  • Step 3: Substitute the value of n into the formula. Here, n = 5.
  • Step 4: Calculate n^2. So, 5^2 = 25.
  • Step 5: Multiply the result by 2. Therefore, 2 * 25 = 50.
  • Step 6: Conclude that the maximum number of electrons that can be accommodated in the shell with n=5 is 50.
