Answer

Explanation:

Step1: Recall orbital - sub - level rules

The number of orbitals in s sub - level is 1, in p sub - level is 3, in d sub - level is 5 and in f sub - level is 7.

Step2: Determine orbitals for each energy level

  • For n = 1, only s sub - level exists. So s = 1, p = 0, d = 0, f = 0, total = 1.
  • For n = 2, s and p sub - levels exist. s = 1, p = 3, d = 0, f = 0, total = 1 + 3=4.
  • For n = 3, s, p and d sub - levels exist. s = 1, p = 3, d = 5, f = 0, total = 1+3 + 5=9.
  • For n = 4, s, p, d and f sub - levels exist. s = 1, p = 3, d = 5, f = 7, total = 1+3 + 5+7 = 16.

Step3: Recall maximum electrons per energy level

The maximum number of electrons in an energy level n is given by 2n².

  • For n = 1, 2n²=2(1)² = 2.
  • For n = 2, 2n²=2(2)² = 8.
  • For n = 3, 2n²=2(3)² = 18.
  • For n = 4, 2n²=2(4)² = 32.

Step4: Recall orbital shapes

The p sub - level has a dumb - bell shape.

Step5: Recall same - shaped sub - levels

Sub - levels with the same letter have the same shape. So 2s and 3s have the same shape (spherical).
