What is the simple definition of metalloid?
metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal. There is no single property which can be used to unambiguously identify an element as a metalloid.
What is metalloid and example?
Elements which show some properties of metals and some other properties of nonmetals are called metalloids. Metalloids look like metals but they are brittle like non metals. They are also called as semi metals. Some important examples of metalloids are as follows : Boron(B), Silicon(Si) and Germanium(Ge).
What are 2 examples of metalloids?
Boron, silicon, germanium, arsenic, antimony, and tellurium are commonly recognised as metalloids. Depending on the author, one or more from selenium, polonium, or astatine are sometimes added to the list.
What is the definition of metalloids for Class 8?
Metalloids are the smallest class of elements, containing just six elements. They fall between metals and nonmetals in the periodic table. Metalloids may act either like metals or nonmetals in chemical reactions. Most metalloids have some physical properties of metals and some physical properties of nonmetals.
What is metalloids class 9th?
Definition of Metalloids Metalloids are a small group of elements founds in the periodic table of elements along the zigzag line that distinguishes metals from non-metals and is drawn from between boron and aluminium to the border polonium and astatine.
What are metalloids class 10th?
Metalloids can be defined as chemical elements whose physical and chemical properties fall in between the metal and the non metal categories. Boron, germanium, silicon, antimony, arsenic, and tellurium are the six most widely recognized metalloids.
What is metalloid Class 9?
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.
What is a metalloid Class 10?
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.
What are metalloids Class 9?
Why is polonium a metalloid?
Polonium has a position in the periodic table that could make it a metal, a metalloid or a nonmetal. It is classed as a metal as its electrical conductivity decreases as its temperature rises….

What are metalloids chemistry class 9?
What are compound class 9?
Compound is a pure substance made up of two or more elements combined chemically in a definite ratio. Characteristics: Compound has fixed melting point and boiling point. 3. Compound is a homogeneous substance.
What makes an element a metalloid?
A metalloid is an element with properties in between, or that are a mixture of, those of metals and nonmetals, and which is therefore hard to classify as either a metal or a nonmetal. This is a generic definition that draws on metalloid attributes consistently cited in the literature.
What is the most useful property of a metalloid?
Key Concept: The most useful property of the metalloids is their varying ability to conduct electricity. • Metalloids are elements that have some properties of metals and some properties of nonmetals. Metalloids are found in the periodic table along the zigzag line between the metals and the nonmetals .
What are some uses of metalloids?
Boron (B) Boron is used in the production of borosilicate glass.
What do metals metalloids have in common?
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.
