Direction (Q. Nos. 16 and 17) This section contains a paragraph, describing theory, experiments, data, etc. Two questions related to the paragraph have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).

Passage

Group 17 elements are known as halogens ( sea salt forming). Their general configuration is ns²np⁵ where, n = 2 to 7. Fluorine is the first member of the group differs in several ways from the rest of the group. Halogens are highly reactive elements having strong affinity for hydrogen. All the halogens form both ionic and covalent compounds .Fluorine is always monovalent and shows -1 oxidation state in its compounds .The other halogens exhibit 1, 3, 5, 7 valencies in their compounds and show - 1 to + 7 oxidation states.

Q. Valence shell configuration that belongs to most reactive non-metal is
