Question

Which group is more reactive than the alkaline earth metals?

Answer 1

Answer: Alkaline metals(Group 1)

Step-by-step explanation:

These elements react vigorously with cold water to give hydrogen gas and they have one electron in their outer-most shell which allows them to give electron freely and are good reducing agents.

examples of these elements are:

Hydrogen

Lithium

Sodium

Potassium

Rubidium

Hydrogen is the only gas in group 1.

Answer 2

Answer: The alkali metals reactivity is generally higher than the alkaline earth metals.

Explanation: This makes the alkaline earth metals with their two valence electrons less reactive than alkali metals with their one valence electron.

Alkali metals is ns1 and alkaline earth metals is ns2
