In general they are poor conductors of heat and electricity. They tend to be Brittle - if a solid. They are usually Non-ductile unlike metals which are. They tend not to be lustrous May be Solids, liquids or gases at room temperature.

Nonmetals are generally not shiny. They tend to be dull.
Well, nonmetals are opaque and brittle. They are also bad conductors of heat and electricity.

Brittleness is a property that is characteristic of many nonmetals and few metals. Metals are typically malleable and ductile, able to be bent and stretched without breaking, whereas nonmetals are often brittle and prone to shattering when subjected to force.
Many nonmetals are brittle and Carbon is a non metal. Charcoal is a carbon compound so charcoal is brittle having the physical property of carbon.
nonmetals because hydrogen is a gas
Brittle
These chemical elements are nonmetals.
Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily. Nonmetals display a wide range of chemical properties and reactivities.High ionization energyPoor thermal conductorThey are negatively chargedPoor electrical conductor
