Which property best distinguishes a nonmetal from a metal?

Solid nonmetals are brittle, as opposed to metals, which are generally ductile or malleable. Nonmetals usually have lower densities than metals; are mostly poorer conductors of heat and electricity; and tend to have significantly lower melting points and boiling points.

What are the chemical properties of non-metals?

Chemical Properties of Nonmetals

  • Nonmetals are poor conductors of heat and electricity.
  • Unlike metals, nonmetals aren’t malleable and ductile.
  • Nonmetals react more with metals than with nonmetals.
  • Usually, nonmetals react with other nonmetals in high temperature.
  • Most nonmetals do not react with air in room temperature.

Which of these is a distinguishing property for the nonmetals?

Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite).
