Question

group 2 elements have two valence electrons. which kind of bond will they most likely form, and why? (1 point) an ionic bond is likely because they will want to give away two valence electrons in order to become stable. a covalent bond is likely because they want to share those two valence electrons in order to become stable. an ionic bond is likely because they are metals and will want to bond with nonmetals. a metallic bond is likely because they are metals and can bond with other metals.

Explanation:

Group 2 elements are metals. They have two valence - electrons. To achieve a stable electron configuration (octet rule), they are likely to give away these two valence electrons. When they give away electrons, they form positive ions. Non - metals are likely to gain electrons. Ionic bonds form between a metal (which loses electrons) and a non - metal (which gains electrons). Covalent bonds involve sharing of electrons and metallic bonds are between metal atoms. So, Group 2 elements are most likely to form ionic bonds.

Answer:

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