Question

There are three metals x y and z .x less reactive than y and z is more reactive than x and y . Find x y and z

Answer 1

Answer:

Alkali metals are the most reactive metals, therefore X is an alkali metal. (e.g: Na or K)

Alkaline Earth metals are most reactive than other metals except alkali metals, therefore Y is an alkaline earth metal. (e.g: Mg or Ca)

Z is any other metal less reactive than alkali and alkaline earth metals but more active than hydrogen. (e.g: Fe)

The increasing reactivity series can be written as: X > Y > Z.
