Properties of a nonmetal

Answer 1

Generally, non-metals have/are:

- low electrical conductivity

- low thermal conductivity

- lower density

- brittle (in solid form)

- dull (in solid form)

- low melting points and low boiling points

- high electronegativity

- negative valency

They also form they form acidic oxides, whereas metals form basic oxides.

Answer 2

malleable, brittle, poor conductors, low boiling and melting points, high electronegativity, low densities
