The Correct Option is A
Solution and Explanation
Element with atomic number 117 is Tennessine (Ts).
It belongs to Group 17 (Halogens) in the periodic table.
Group 17 elements have 7 valence electrons, with the configuration ending in \(ns^2 np^5\).
It belongs to Group 17 (Halogens) in the periodic table.
