Question

what is reactivity series and write the least and most reactive metals

Answer 1

Reactivity series is a series of metals in order to reactivity where metals are arranged in the decreasing order of reactivity. Hence, most reactive metal is kept on the top of the series and least reactive metal is kept in bottom.
- And the most reactive metal is potassium(k) and least is gold(Au)

Answer 2

hi
Reactivity serier: The arrangement of metals in a vertical column in the order of decreasing reactivities .

Most reactive metal is potassium
Least reactive metal is platinum
have a nice day
