Question

on the basis of quantum number, justify that the sixth period of the periodic table should have 32 elements?​

Answer 1

Answer:

In the 6th period, electrons can be filled in only 6s, 4f, 5d, and 6 p subshells. ... According to Pauli's exclusion principle, each orbital can accommodate a maximum of 2 electrons. Thus, 16 orbitals can accommodate a maximum of 32 electrons. Hence, the sixth period of the periodic table should have 32 elements.
