What are the Properties of
Metalloids? Definition of Metalloids
What is the definition of
Metalloids? The Metalloids, or semi-metals, are elements with properties
intermediate between metals and non-metals.
Elements
in the Metalloids Group
The
Physical and
Chemical Properties are the
characteristics of a group, like Metalloids, which distinguishes it from the
other groups in the Periodic Table. Refer to the article on
Metalloids for additional information and facts about this
group of elements.
The elements and their position in the Periodic Table are shown
in the following Metalloids Chart.

Properties of Metalloids
- What are the Physical Properties of Metalloids?
What are the Physical
Properties of Metalloids? The Physical properties of Metalloids are the characteristics
that can be observed without changing the substance of the elements in a
group into other
substances. Physical properties are usually those that can be observed using our
senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
Metalloids have mixed properties which are difficult to characterize. The Physical Properties
that are generally associated with
Metalloids are as follows:

Properties of Metalloids - What are the Chemical Properties of Metalloids?
What are the Chemical
Properties of Metalloids? They are the characteristics that
determine how they will react with other substances or change from
one substance to another. The better we know the nature of the substance the
better we are able to understand it. Chemical properties are only observable during a
chemical reaction. Reactions to substances may be brought
about by changes brought about by burning, rusting, heating, exploding, tarnishing
etc. The Chemical
Properties of Metalloids are as follows:
|
What are the Chemical Properties of
Metalloids? |
|
Oxidation |
Readily form glasses |
| Alloys |
Form alloys with metals |
| *Allotropic |
Several metallic and
non-metallic allotropic forms |
| Melting |
Some metalloids
contract on melting |
| Compounds |
Reacts with the halogens to
form compounds |
*Allotropic - Allotropes are
forms of an element with different physical and chemical properties
occurring in two or more crystalline forms in the same physical state.
