metalloid
metal
nonmetal
choices
an element that generally lacks luster, is brittle or gaseous at
room temperature, and is a poor conductor of heat and
electricity.
an element that typically has a shiny appearance, is solid at
room temperature, malleable, ductile, and conducts heat and
electricity very well
an element with properties that are intermediate between
those of metals and nonmetals.

Explanation:

Metalloid: An element with properties intermediate between metals and nonmetals.
Metal: An element with shiny appearance, solid at room - temp, malleable, ductile, good heat/electricity conductor.
Nonmetal: An element lacking luster, brittle/gaseous at room - temp, poor heat/electricity conductor.

Answer:

Metalloid: an element with properties that are intermediate between those of metals and nonmetals.
Metal: an element that typically has a shiny appearance, is solid at room temperature, malleable, ductile, and conducts heat and electricity very well.
Nonmetal: an element that generally lacks luster, is brittle or gaseous at room temperature, and is a poor conductor of heat and electricity.
