Question

define reactive serices with example​

Answer 1

Answer:

The reactivity series is a series of metal elements, and sometimes carbon and hydrogen, that is arranged according to their reactivity. A reactivity series is typically a vertically presented model with the most-reactive element placed at the top of the series and the least-reactive element placed at the bottom.

Answer 2

In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.
