Question

06. On the basis of electronic configurations, justify that the second and third periods
contain 8 elements each, fourth and fifth periods contains 18 elements each and
the sixth period contains 32 elements.​

Answer 1

Answer:

In the sixth period (n = 6) of the periodic table, 6s, 4f, 5d and 6p orbitals are filled in the increasing order of the energy. Total 16 orbitals are available each of which contains a maximum 2 electrons. Thus, the sixth period can accommodate maximum 32 elements
