What is a metalloid give three examples?

Metalloids are elements which show some properties of metals and some properties of non-metals. Examples: Silicon, boron, arsenic, antimony, germanium, tellurium, polonium.

What are common metalloids?

Summary

• Metalloids are elements with properties intermediate between those of metals and non-metals.
• Silicon is a metalloid because it has luster, but is brittle.
• Boron, arsenic, and antimony are metalloids with a variety of uses.

What is the most common metalloid on our planet?

Silicon is the “big sister” to carbon, and shares many of the same chemical properties. For this reason, silicon is known as a chemical analogue to carbon. But unlike carbon, silicon a metalloid — in fact, it’s the most common metalloid on earth.

What are metalloids give examples Class 10?

Metalloids are typically semiconductors which means that they both insulate and conduct electricity . The semiconductor property makes metalloid very useful as a computer chip material . They are also called as semi metals. Some important examples of metalloids are as follows : Boron(B), Silicon(Si) and Germanium(Ge).

• The least abundant natural metalloid is tellurium.
• Metalloids are valuable in the electronics industry.
• Arsenic and polonium are highly toxic metalloids.

What metalloid is used in glass?

Antimony
Antimony is the metalloid which is used to make glasses.

What are the metalloids give one example?

Metalloids look like metals but they are brittle like non metals. Metalloids are typically semiconductors which means that they both insulate and conduct electricity . Some important examples of metalloids are as follows : Boron(B), Silicon(Si) and Germanium(Ge).

What are metalloids give examples Class 9?

Elements which show properties of both metals and non-metals are called metalloids. For example: Silicon, Germanium.

– Carbon – Aluminium – Selenium – Polonium – Astatin

What are three common uses of metalloids?

Uses of Metalloids. The most important use of antimony is in the making of flame retardants. It is used in aircraft, automobile seat covers, light aircraft engine covers, etc. It is used with lead to increase the hardness and mechanical strength of lead which is used in acid batteries.
