Question

identify four characteristics of nonmetals.
they react easily with hydrogen atoms.
they are soft and pliable.
they exist only in liquid or gas states.
they include examples of elements that are molecules.
when in a solid state, nonmetals are usually brittle.
they include halogens and noble gases.
they do not conduct heat very well.

Explanation:

Non - metals have several characteristic properties. They can form molecular elements. In solid state, they are brittle. Halogens and noble gases are non - metals. Also, they are poor heat conductors.

Answer:

They include examples of elements that are molecules.
When in a solid state, nonmetals are usually brittle.
They include halogens and noble gases.
