Question

Which of the following is/are salient features of the activity series?

• A. Electropositive character reduces down the series
• B. A salt of a metal higher up in the series is displaced by lower metal
• C. Reducing power of metals decreases down the group
• D. The tendency of metal to lose electrons decreases down the group.

Answer 1

Answer: (A), (C), (D)

The correct options are
A

Electropositive character reduces down the series

C

Reducing power of metals decreases down the group

D

The tendency of metal to lose electrons decreases down the group.

The arrangement of metals in decreasing order of reactivity in the form of series is known as activity series. Electropositive character, reducing power and tendency of metals to get oxidize decreases down the reactivity or activity series because as we move down in reactivity series the tendency to donate electrons reduces.
