Answer:

About half of the non-metals are gaseous at room temperature, and pressure.

Explanation:

There are about a 100 or so elements; most of which are metals. All of these metals, with one or two exceptions are solids under the given conditions. Can you think of a metal that is not a solid at room temperature and pressure?

Of the non-metals, of which there are only about 20 or so, there are 12 (or 11) that are gaseous at room temperature and pressure. We can list these: dihydrogen, dinitrogen, dioxygen, #X_2, (X=F, Cl)#, and the seven (or actually 6) #"Noble Gases"#.
