not only are there two but four:
Two properties of non-metals are that they are brittle solids and they are dull in appearance or not lustrous. Non-metals can be gases, solids, or liquids at room temperature.
They are generally dull in color (not shiny) and they are rigid, meaning that they do not bend well, but rather snap.
high ionization energy and poor electrical conductivity
they are good oxidising agents.
brittle.
generally poor conductors of heat and electricity.
have low density.
what are two physical properties about minerals
Nonmetals.
Poor conductors of heat and electricity.Brittle - if a solid.Nonductile.Do not possess metallic luster.Transparent as a thin sheet.Solids, liquids or gases at room temperature.
Most nonmetals are poor conductions of electricity and heat and are reactive with other elements. Solid nonmetals are dull and brittle.
Yes, nonmetals (excepting noble gases) are reactive chemical elements.
These chemical elements are nonmetals.
Nonmetals are generally not shiny. They tend to be dull.
Well, it's a gas, so its properties are closer to nonmetals.
nonmetals because hydrogen is a gas
Most nonmetals are poor conductions of electricity and heat and are reactive with other elements. Solid nonmetals are dull and brittle.
The properties of nonmetals also tend to vary more from and element to element than do the properties of the metals
Well, nonmetals are opaque and brittle. They are also bad conductors of heat and electricity.
Physical properties of metals include: luster, malleability, and ductility. Chemical properties include: forming cations, and reacting with nonmetals to form ionic compounds.
what are two physical properties about minerals
Nonmetals lack most of the properties of a metal.
because metalloids usually have properties that are similar to metals and nonmetals
i think they have properties of both metals and nonmetals .
