4. (a) What do you understand by the term
non-metal?
(b) State any five physical properties of a
non-metal.​

Answer 1

Answer:

In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. ... Metalloids such as boron, silicon, and germanium are sometimes counted as nonmetals.

Explanation:

Physical Properties of Non-metals

Poor conductors of electricity and heat.

Non-Ductile metals.

Brittle solids.

Maybe solids, liquids or gases at room temperature.

Answer 2

Answer:

Physical Properties of Nonmetals

They have high electronegativities. Nonmetals are insulators which means that they're poor conductors of electricity. They are dull, they do not have lustre like metals. Nonmetals are poor conductors of heat.
