* Brittle: Nonmetals tend to be brittle, meaning they break easily when subjected to stress. This is because their bonding structures are not as strong or flexible as metals.
* Poor conductors of heat and electricity: Nonmetals are generally poor conductors of heat and electricity. This is due to their tightly bound electrons, which are not easily freed to carry charge.
* Low melting and boiling points: Nonmetals tend to have lower melting and boiling points compared to metals. This is because the bonds between their atoms are weaker.
* Dull appearance: Nonmetals often have a dull or non-reflective surface. They don't have the characteristic shine of metals.
* Varying densities: Nonmetals have a wide range of densities, some being quite light (like sulfur) and others being denser (like carbon in diamond form).
Exceptions:
While these characteristics are common to many nonmetals, there are exceptions:
* Carbon in its diamond form is extremely hard and has a high melting point, making it an exception to the "brittle" and "low melting point" characteristics.
