Question

3
antimony is like a nonmetal in that it is a brittle, crystalline solid, has poor electrical and heat conductivity, and has a low boiling point.
however, it is also like a metal because of its shiny silver appearance and ability to form alloys.
into which of the following groups should antimony be placed?
a. metalloids
b. transition metals
c. alkali metals
d. halogens
reset submit

Explanation:

Metalloids are elements with properties of both metals and nonmetals. Antimony has nonmetallic traits (brittle, poor conductivity, low boiling point) and metallic traits (shiny appearance, alloy formation), fitting the metalloid category. Transition metals, alkali metals, and halogens do not exhibit this mixed set of properties.

Answer:

A. metalloids
