Question

Identify the correct alternative from the following set of properties that increase down the group.
(a) Atomic radius
(b) Ionization potential
(c) Electron affinity
(d) Electropositivity
(e) Oxidizing property
(f) Reducing property

• A. a, b and c
• B. c, d and e
• C. b, c and e
• D. a, d and f

Answer 1

The correct option is D a, d and f

The atomic size increases down the group as more shells are added. Their tendency to lose the electron increases down the group as the valence electron is very losely bound and this increases their electro positivity and reducing power.
