Question

Which family of elements contains metals, nonmetals and metalloids?

Answer 1

Looking at the arrangement of elements on the periodic table we find that there are three families or groups that have a metal, a metalloid and a non-metal in the set of elements.

Group 14 (Row) IVA has
Carbon a non-metal
Silicon and Germanium both metalloids
and Tin and Lead both metals

Group 15 (Row) VA has
Nitrogen and Phosphorus both non-metals
Arsenic and Antimony both metalloids
and Bismuth a metal

Group 16 (Row) VIA has
Oxygen, Sulfur and Selenium all non-metals
Tellurium a metalloid
and Polonium a metals

I hope this was helpful.
