What are Metalloids? Define Metalloids
Metalloids is a term used in Periodic Chemistry when classifying the chemical elements. Each element can usually be classified as a metal or a non-metal based on their general Physical and Chemical Properties. However, metalloids have mixed properties which can be harder to characterize. The word Metalloids is derived from the Latin word ‘metallum’ meaning “metal” and the Greek word ‘oeides’ meaning “resembling in form or appearance”.

What are Metalloids? Common Properties of Metalloids
The terms brittleness, semi-conductivity and metallic lustre are often used as distinguishing indicators of metalloid status. Some metalloids also contract on melting, unlike many other types of metals. They can also form alloys with metals.
