Group 2 elements have two valence electrons. Which kind of bond will they most likely form, and why?(1 point)

Question

Responses

An ionic bond is likely because they will want to gain two electrons to become stable.

A covalent bond is likely because they want to share those two valence electrons in order to become stable.

A metallic bond is likely because they are metals and can bond with other metals.

An ionic bond is likely because they will want to give away two valence electrons in order to become stable.

Answer 1

The correct response is:

An ionic bond is likely because they will want to give away two valence electrons in order to become stable.

Group 2 elements, or alkaline earth metals, typically have two valence electrons. To achieve a stable electron configuration (like that of a noble gas), they will tend to lose these two valence electrons, forming positively charged ions (cations) and creating ionic bonds with nonmetals that will accept those electrons.
