According to Pauli's exclusion principle, each orbital can accommodate a maximum of 2 electrons. Thus, 16 orbitals can accommodate a maximum of 32electrons. Hence, the sixth period of the periodic table should have 32 elements.

In 6th period, electrons are filled in 6th energy shell.
The electrons are filled in the subshells following the sequence: 6s - 4f - 5d - 6p
Number of orbitals in the sub shells are:
6s : 1
4f : 7
5d : 5
6p : 3
Total orbitals = 1+7+5+3 = 16 orbitals
Each orbital can have maximum of 2 electrons. So total electrons that can be filled in the sixth period = 16 × 2 = 32
So we can accommodate 32 elements in the 6th period.
