Yes, nonmetals are generally brittle. This means they tend to break or shatter when subjected to stress or force, rather than bending or deforming like metals.

In general, non-metals are brittle, dull, and poor conductors of heat and electricity. They tend to have lower melting points than metals. Most of non-metals exist in two of the three states of matter at room temperature: gases and solids, except bromine, which exists as a liquid.
