Provide information regarding the electronic configuration and atomic and ionic radii of the elements of group $16$.

(N/A) Electronic Configuration: The elements of group $16$ have six electrons in their outermost shell,and their general electronic configuration is $ns^2 np^4$.
Atomic and Ionic Radii: As we move down the group,the number of shells increases,leading to an increase in atomic and ionic radii. However,the oxygen atom is exceptionally small in size.
