What best describes the states of nonmetals when they are at room temperature? most nonmetals are gaseous, but some are liquid or solid. all nonmetals are gaseous unless they bond with a metal. most nonmetals are solids, but some are gaseous or liquid. all nonmetals are solid unless they bond with a metal.

Option (a) is the correct answer.

Explanation:

Non-metals are the substances that are deficient in electrons as compared to metals.

For example, carbon, selenium, bromine, chlorine, phosphorous etc are all non-metals.

At room temperature, hydrogen, helium, fluorine, chlorine etc all exist as gases. Whereas some non-metals exist as solid like carbon, phosphorous, sulfur, selenium, iodine etc.

But bromine exist as a liquid.

Hence, we can conclude that the statement Most nonmetals are gaseous, but some are liquid or solid, is true.

the answer is false
