Question

On the basis of the metal activity series name the following.

Alkali metal of the second period.

Answer 1

1. The elements which are able to lose or donate electrons present in its valence shell are metals.
2. Based on their ability to lose electrons metals are arranged in the decreasing order of their reactivity and are called the reactivity series.
3. The alkali metal present in the second period of the periodic table is lithium.
4. Lithium is the most reactive metal present in the top list of reactivity series because it has the tendency to lose electrons faster.

So, the alkali metal of the second period is lithium.
