Question

Which of the following statements about alkali metals is true?

alkali metals have full valence shells

alkali metals form 1- cations

alkali metals are very reactive

alkali metals form 2- cations

Answer 1

Very reactive I think

Answer 2

Answer: OPTION C, Alkali metals are more reactive.

Step-by-step explanation:

Since alkali or IA group elements are more electropositive and they readily loose Electrons to form monocation. Hence they are very reactive.

Their valency shell configuration is ns1, incomplete.

They forms only monocations like Na+, K+ etc

Alkaline earth metals forms +2 ions
