Which one of the following does not increase while moving down the group of the periodic table?

(a) Atomic radius
(b) Metallic character
(c) Valence
(d) Number of shells in an element

Answers (1)

Ans (c)
Sol

Atomic radius increases down a group
Metallic character increases down a group
The number of electrons in the outer most shell are same in a group hence valence electrons and valency of all the elements in the group remains the same when we move from top to bottom.
Number of shells in an element increases down a group

Hence option (c) is correct.
