Which element is an example of a metalloid? a) gold b) helium c) iron d) silicon

D) Silicon is an example of a metalloid.

It has some of the properties of metals and some of the properties of nonmetals.

In the Periodic Table, metalloids sit on either side of a zig-zag line separating metals from nonmetals.

In the diagram below, Fe and Au are metals, while He is a nonmetal.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
