JEE Main Chemistry question

Elements of group 1 and group VI in the periodic table have one thing common. That is with the increasing atomic number, the:

(A)Maximum valency increases
(B)Reactivity increases
(C)Atomic radius increasesCorrect
(D)Oxidizing power increases

Answer: (C)

Solution

Atomic radius increases down any group in the periodic table as successive electron shells are added, a trend shared by group 1 (alkali metals) and group 16 (chalcogens) alike, regardless of their very different chemical behaviour otherwise. Reactivity trends oppositely for metals versus non-metals down a group
