Question

Which properties are characteristics of nonmetals?

A) malleable
B) brittle
C) solid at room temperature
D) low density
E) electrical insulator
F) thermal conductor

Answer 1

Nonmetals are poor conductors of heat and electricity, brittle when solid, and are good electrical insulators. Unlike metals, they can appear dull and are not good thermal conductors.

Step-by-step explanation:

Characteristics of nonmetals include their being poor conductors of heat and electricity, largely due to their nature as good electrical insulators.

They are generally brittle when solid, as opposed to metals which are malleable and ductile. Unlike metals that are typically shiny and good thermal conductors, nonmetals can appear dull and lack malleability, making them unable to be shaped into wires or sheets.

Examples of nonmetals include sulfur, bromine, and helium, each exhibiting these common nonmetallic properties.
