Why non-metals gaseous at room temperature?

Answer 1

The atoms of non-metals are covalently bonded in a molecule. These molecules are joint by weak intermolecular forces of attraction which are easily overcame. Hence the boiling point is low and usually below room temperature so at room temperature, they are gaseous.

Answer 2

Some are, but not all. Examples:

1 Carbon is a nonmetal and is solid at room temp.,

2 Bromine, a nonmetal, is a liquid at room temperature,

3 Halogens and Noble Gases are nonmetals and exist as gases at room temp.

all the non-metals, with the exception of bromine, are either in gaseous or solid state at room temperature. So, only about 50% of the non-metals are gases at room temperature.

Answer 3

Non-metals are gaseous at room temperature because they typically have weak intermolecular forces between their atoms, which allows them to easily break apart and move freely as gas molecules. In contrast to metals, which tend to have strong metallic bonds holding their atoms together, non-metals have covalent bonds that are weaker and more easily broken.

Answer 4

No, although most are.
No. they are not all gases. e.g. carbon, silicon, phosphorous, sulfur, Iodine (all solids), bromine (liquid).

Answer 5

No, not all of them. But all gases at room temperature are nonmetals.

Answer 6

No.

Carbon, phosphorus, sulfur, and iodine are nonmetal elements that are solid at room temperature.

Answer 7

Nonmetals are gases but also solids.
