Is it the following sentence true or false four of the nonmetals are gases at room temperature?
False.
Why non-metals gaseous at room temperature?
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.
What are the physical properties of nonmetals?
Poor conductors of heat and electricity.Brittle - if a solid.Nonductile.Do not possess metallic luster.Transparent as a thin sheet.Solids, liquids or gases at room temperature.
Most of these are in gas form at room temperature?
Nonmetals
Are nonmetals a state of matter at room temp?
Everything has a 'State of Matter' be it Solid, Liquid or Gas. Non-metals are either gases or solids, with the exception of Bromine , which os a liquid.
What are most nonmetals at room temperature?
Gases at room temperature
Are many of nonmetals are gases at room temperature?
Nonmetals are gases but also solids.
What class of element includes all of the elements that are gases at room temperature?
All the members of the noble gases family (group 18 of the periodic table) are gases at room temperature.
What Unlike metals many nonmetals are?
Unlike metals, most nonmetals are gases at room temperature.
Is it the following sentence true or false four of the nonmetals are gases at room temperature?
False.
Are gases at room temperature nonmetals?
Yes.
Why non-metals gaseous at room temperature?

What non metals at room temp?
Most non metals are usually liquids or gases at room temperature, although not specifically one or the other. It depends on the properties of the substance. Most metals are solids at room temperature, with the exception of Mercury.
What are three general characteristics if nonmetals?
Nonmetals are generally the opposite of metals. They are very brittle, are not good conductors of heat and electricity, and are dull. Most nonmetals are gases at room temperature, which means they have low boiling points. They have lower densities than nonmetals.
Are most nonmetals are liquid?
Most nonmetals are not liquid at room temperature, as they are gasses. The only nonmetal that is in a liquid state at room temperature is bromine.
What are the physical properties of nonmetals?
Poor conductors of heat and electricity.Brittle - if a solid.Nonductile.Do not possess metallic luster.Transparent as a thin sheet.Solids, liquids or gases at room temperature.
Is the following sentence true or false four the number nonmetals are gases at room temperature?
It is neither, it is simply grammatically poor and makes little sense.
