each element that forms cations is a metal, except for one (hydrogen), while each element that forms anions is a nonmetal. This is actually one of the chemical properties of metals and nonmetals: metals tend to form cations, while nonmetals tend to form anions

Answer:

6.C

7.D

8.D

Explanation:

6. Chlorine is a non-metal, so is helium is inert hence Chlorine is the correct answer.

7.Group 18 elements are noble gases with maximum electron configuration hence they do not bond further

8.During bonding metals transfer  electrons i.e. they become less negative and more positive thus having a positive ion
