Question

Which option represents the correct characteristics of metals?

• A. Metals have good electrical and thermal conductivity.
• B. Metals have low density
• C. Metals are brittle
• D. Metals are not ductile

Answer 1

The correct option is A

Metals have good electrical and thermal conductivity.

A metal is a material (an element) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity.

Metals are generally malleable: they can be hammered or pressed permanently out of shape without breaking or cracking. Metals are generally ductile: they can be drawn out into long, thin wires.

About 91 of the 118 elements in the periodic table are metals.
