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

Detailed Solution for Test: General Properties of Group-17 (Halogens) - Question 16

All the halogens are highly reactive. They react with metals and non-metals to form halides due to readily acceptance of an electron

Test: General Properties of Group-17 (Halogens) - Question 25

Direction (Q. No. 25) This section is based on Statement I and Statement II. Select the correct answer from the codes given below.

Q. 

Statement I : All halogens are coloured.

Statement II : Halogens absorbs part of the light in the visible region.

Detailed Solution for Test: General Properties of Group-17 (Halogens) - Question 25

Halogen molecule absorbs light in the visible region as a result of which their electrons are excited to higher energy level while the remaining light is transmitted.
