Answer:
The sixth period corresponds to the filling of principal energy
level 6, i.e., \[n=6\] or \[6s,\text{ }6p,\]\[6d\] and \[6f-\]orbitals. The \[6d\]
and \[6f-\]orbitals have higher energy than 7\[7s-\]orbital. Thus, \[6d\] and \[6f-\]orbitals
are not filled. However, before \[6p-\]orbitals \[4f\] and \[5d\]-orbitals
which have energies between 6s and \[6p-\]orbitals are being filled. Thus,
sixteen orbitals, i.e., \[6s,4f,5d\] and \[6p\]-orbitals receive electrons
corresponding to 32 elements. Therefore, sixth period accommodates 32 elements.
