On the basis of quantum numbers, which of the following options explain that the sixth period of the periodic table should have 32 elements?

Options

  1. AIn the 6th period, electrons can be filled in only 6s, 4f, 5d, and 6 p subshells i.e.16 orbitals and 32 electr
  2. BThe sixth period contains elements with atomic numbers ranging from 57 to 88.
  3. CThe quantum numbers do not predict the existence of 32 distinct elements in the sixth period.
  4. DThe sixth period is the first period to include elements with an f-block.

Correct answer

A. In the 6th period, electrons can be filled in only 6s, 4f, 5d, and 6 p subshells i.e.16 orbitals and 32 electr

Step-by-step solution

Correct Option is : (A) In the 6th period, electrons can be filled in only 6s, 4f, 5d, and 6 p subshells i.e.16 orbitals and 32 electrons.
