Nonmetal Elements Quiz

Some typical properties of nonmetals include low density, high electronegativity, poor conductivity of heat and electricity, and brittle or crumbly solid state.

Some examples of nonmetallic elements are hydrogen, carbon, nitrogen, oxygen, and silicon.

Oxides of nonmetals tend to be acidic, while oxides of metals tend to be basic.

<p>Nonmetals tend to have low density, high electronegativity, and are often poor conductors of heat and electricity. They can range from colorless gases like hydrogen to shiny solids like the graphite form of carbon. In contrast, metals are good conductors and most are pliable.</p> Signup and view all the answers
