d) Non-brittle

Solutions

Expert Solution

Answer : a) Poor conductors of heat and electricity

Explanation :

Metalloids are those which posseses the properties of metals and non-metals.

Properties of Metalloids :

They are non-malleable.
They are non-ductile.
They are brittle.
Poor conductors of heat.
Poor conductors of electricity. but compare to metals but are better conductors than non-metals.

a) Poor conductors of heat and electricity
