1 : an element intermediate in properties between the typical metals and nonmetals. 2 : a nonmetal that can combine with a metal to form an alloy.
Metalloids are elements which show some properties of metals and some properties of non-metals. Examples: Silicon, boron, arsenic, antimony, germanium, tellurium, polonium.
A metalloid is a chemical element that exhibits some properties of metals and some of nonmetals. In the periodic table metalloids form a jagged zone dividing elements that have clear metallic properties from elements that have clear nonmetallic properties.
Metalloids are the elements which are having a combination of some properties of metals along with some properties of nonmetals. Their properties are intermediate between the properties of metals and nonmetals, they are also called semi-metals. Example: – Boron, Silicon, Germanium, etc.
The elements which display properties of both metals and non-metals are classified as metalloids. In the Periodic Table, they separate metals from the non-metals. For eg. Silicon, Arsenic etc. webew7 and 63 more users found this answer helpful.
Metalloids are the smallest class of elements rather than others two classes of elements that's are metals and non metals. Metalloids are the compound which show properties in between metals and non metals . It look like metals but mostly behave like non metals . They are also called as semi metals .
The elements which are found in the step-like line between metals and nonmetals of the periodic table are known as the metalloids. They are: antimony (Sb), germanium (Ge), silicon (Si), arsenic (As), tellurium (Te), polonium (Po), boron (B), and astatine (At).
Elements which show properties of both metals and non-metals are called metalloids. For example: Silicon, Germanium.
Grade 8. A metalloid is a chemical element that exhibits some properties of metals and some of nonmetals. Definition for metalloids: elements with properties intermediate between metals and nonmetals. Boron, silicon, germanium, arsenic, antimony, tellurium, and polonium are metalloids.
Properties. Metalloids usually look like metals but behave largely like nonmetals. Physically, they are shiny, brittle solids with intermediate to relatively good electrical conductivity and the electronic band structure of a semimetal or semiconductor.
Five Main Properties of Metalloids

Most metalloids have a metallic lustre but are poor conductors of heat and electricity.
varying ability to conduct electricity
The most useful property of metalloids is their varying ability to conduct electricity. Whether or not a metalloid conducts electricity can depend on the temperature or the exposure to light. For this reason metalloids, such as silicon or germanium, are used to make semiconductors.
Metalloids are unique because they have properties of both metals and non-metals. For example, boron acts as a nonmetal when it reacts with sodium, but it acts as a metal when it reacts with fluorine. Most metals have a characteristic lustre and are good conductors of heat and electricity.
Luster: Metalloids can be either shiny or dull in their appearance. Malleability: Metalloids can be malleable and ductile, like metals. They also can be brittle, similar to nonmetals.
What characteristic of metalloids makes them particularly useful? Metalloids are particularly useful for their ability to conduct electricity with varying efficiency under different conditions.

A series of six elements called the metalloids separate the metals from the nonmetals in the periodic table. The metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. These elements look metallic; however, they do not conduct electricity as well as metals so they are semiconductors.
Metalloids are important to modern technology because they are semiconductors which help make electronics such as computers. What element in the first column of the periodic table is not one of the alkali metals?
