Question

Which group elements is more reactive - alkali metals or alkaline earth metals?​

Answer 1

Answer:

The alkali metals all have a single s electron in their outermost shell. In contrast, the alkaline earth metals have a completed s subshell in their outermost shell. In general, the alkali metals react faster and are more reactive than the corresponding alkaline earth metals in the same period

Answer 2

Answer:

Alkali Metals

Explanation:

It takes more energy to remove two valence electrons from an atom than one valence electron. This makes alkaline Earth metals with their two valence electrons less reactive than alkali metals with their one valence electron.
