Six nonmetallic elements constitute Group 17 (Group VIIa) of the periodic table.
Elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
They carry seven valence electrons in their outermost electron shell and are in two different kinds of orbitals: s (with two electrons) and p (with five).
