True or false & what letter do i circle?

3. True

4.

a. solid non-metals are brittle

b. They have usually lower densities than metals

Explanation:

Non metals are mostly gases. Out of the 17 non-metals, 11 are gases in room temperature. Bromine is the only non-metal that is liquid at room temperature, and the last 5 are solids.

They have lower densities than metals but their densities vary. Solid non-metals are charaterized as brittle.

The last two options are properties of metals, and non-metals show opposite properties, meaning they lack luster (are not shiny) and are poor cnductors of heat and electricity, which is why they are often used as insulators.
