(AKS 2e) Group 2 metals bond with nonmetals or polyatomic ions. What question would a student need to know to form a compound with Group 2 metals? (DOK 2)

Will group 2 elements lose electrons to bond with nonmetals in group 17 in a

1:2 ratio?

Will group 2 elements lose electrons to bond with nonmetals in group 16 in a

2:1 ratio?

Will group 2 elements gain electrons to bond with nonmetals in group 17 in a

1:2 ratio?

Will group 2 elements gain electrons to bond with nonmetals in group 16 in a

2:1 ratio?

Will group 2 elements lose electrons to bond with nonmetals in group 17 in a

1:2 ratio?

Explanation:

Metals are electropositive in nature. This means that they loose electrons. Thus, metals form ionic bonds by loosing electrons to non metals.

Elements of group 2 have a valency of 2 while those of group 17 has a valency of 1 so the ratio in which group 2 elements bond with elements of group 17 is 1:2. Hence the answer.

put the answers   and i could answer.

you gotta add the following molecules so we can give u an answer
