Metalloids

The metalloids are a group of elements in the periodic table. They are located to the right of the post-transition metals and to the left of the non-metals. Metalloids have some properties in common with metals and some in common with non-metals.

What elements are metalloids?

The elements that are generally considered metalloids include boron, silicon, germanium, arsenic, antimony, and tellurium. Other elements such as selenium and polonium are sometimes included as well.

What are the similar properties of metalloids?

Metalloids share many similar properties including: Order of Abundance

The most abundant of the metalloids on Earth is silicon which is the second most abundant element in the Earth's crust after oxygen. The least abundant is tellurium which is one of the rarest stable elements on Earth with an abundance similar to platinum. Here is a list of metalloids in order of abundance in the Earth's crust:
  1. Silicon
  2. Boron
  3. Germanium
  4. Arsenic
  5. Antimony
  6. Tellurium
