Answered by topwriters

(1) Cesium

(2) Iodine

Explanation:

The activity series of metals is an list of metals ranked in order of decreasing reactivity to displace hydrogen gas from water and acid solutions. It can also be used to predict which metals will displace other metals in aqueous solutions.

(1) The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium (Cs).

(2) The least active non-metal of activity series is Iodine (I).
