Metalloids:

Metalloids are the elements found along the stair-step line that separates metals from non-metals. This line is drawn from between Boron and Aluminum to the area between Polonium and Astatine. The Metalloids have properties of both metals and non-metals. Some of the metalloids, such as silicon and germanium, are semi-conductors. This means that they can carry an electrical charge under specific conditions. This property makes metalloids useful in computers and calculators microchips.

This is silicon, a metaloid and a semiconductor.


Non-Metals

Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The non-metals have no metallic luster, and do not reflect light.

Neon is a Non-metal used in signs, lighting and other applications needing light.
