1. they are not good conductors of heat and electricity(except graphite) 2.they are not malleable (cannot be hammered into sheets). 3.they are not ductile(cannot be drawn into wires). 3.they have low densities.
These are called nonmetals (e.g. carbon, phosphorus, sulfur)Metals (such as gold, titanium, and cobalt) are generally lustrous, malleable, and can conduct electricity. Nonmetals are dull, extremely brittle, and are usually (but not always) non-conductive.
A metalloid :)
What is mineral oil and what are its physical properties and its formula
These are examples of physical properties. They are NOT chemical properties!
*isomorphic have different chemical and physical properties and poly morphous have same chemical and physical properties
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
Physical properties of metals include: luster, malleability, and ductility. Chemical properties include: forming cations, and reacting with nonmetals to form ionic compounds.
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 .
Well, nonmetals are opaque and brittle. They are also bad conductors of heat and electricity.
Metalloids, which have properties of both metals and nonmetals. Some metalloids, but not all, conduct heat or electric current.
