Which elements can form acidic compounds? Check all that apply. sulfur rubidium arsenic selenium silicon xenon antimony

Answers

The elements that can form acidic compounds are; sulfur, arsenic, selenium, antimony, silicon.

Acidic compounds are formed by nonmetals. Metallic elements form basic compounds. This means that rubidium does not form acidic compounds since it is a metal.

Also, xenon does not form compounds because it is a noble gas. Noble gases do not react with other elements to form compounds.

However; sulfur, arsenic, selenium, antimony, silicon are nonmetals and they form acidic compounds.
