Metalloids are also known as semi-metals. They possess the following characteristics:
- They are shiny, brittle solids
- They possess intermediate to relatively good electrical conductivity and the electronic band structure of a semimetal or semiconductor.
Metalloids exhibits the external characteristics of a metal, but behaves chemically more as a nonmetal.

- Phosphorus
- Germanium
- Antimony
- Tin
- Arsenic
