Question

HELLO MATES...
What is the significance of the metal at the top of the activity series????​

Answer 1

Metals present at the top of the activity series are more reactive.

Answer 2

metals that are higher on the series will displace metals (in salts) that are lower in the series. An example is the thermite reaction: 2 Al + Fe2O3 → 2 Fe + Al2O3; like many redox reactions, this is highly exothermic). Similarly, tin will replace copper in salts (Sn + CuCl2 → SnCl2 + Cu), not the other way around,
