In the general electronic configuration:

$(\mathrm{n}-2){\mathrm{f}}^{1-14}(\mathrm{n}-1){\mathrm{d}}^{0-1}{\mathrm{ns}}^2$,if value of n =7 the configuration will be :

Following is a general electronic configuration:

$(\mathrm{n}-2){\mathrm{f}}^{1-14}(\mathrm{n}-1){\mathrm{d}}^{01}{\mathrm{n}}^2,$where $(\mathrm{n}=7)$

$5{\mathrm{f}}^{1-14}6{\mathrm{d}}^{01}n{\mathrm{s}}^2$ 

With the successive filling up of the 7s, 5f, 6d, and 7p orbitals, the seventh period (n=7) is similar to the sixth period in that it contains the majority of the radioactive elements created by humans. The element with atomic number 118, which would be a member of the noble gas family, will mark the end of this epoch. After actinium (Z=89), filling up the 5f orbitals results in the 5f-inner transition series known as the actinoid series.
