Arsenic, antimony, bismuth and graphite are all semi-metals. Various compounds such as Mercury telluride are also considered semi-metals.
Note that semi-metals and metalloids are not the same thing (even though arsenic, antimony and bismuth are all metalloids).
If you think to metalloids they are: boron, silicon, arsenic, tellurium, germanium, antimony; some chemists consider selenium, polonium, astatine also as metalloids.
Metalloids and semimetals are not synonyms.
SI, B, As are all solid semimetals at normal conditions
Boron, Silicon,Germanium, Arsenic, Antimony, Tellurium, and Polonium
No, it is a nonmetal.
The 3 main categories are Metal, Nonmetals and Metalloids
The most common semi metal known is silicon. <(*_*)>
A compound is defined as a substance that contains at least two chemical elements and always has a constant mass ratio between elements for each possible pair of the elements that are present in it.
cannot be broken down into other substances
elements are classified in the ?
Nitrogen is not a semimetal.
How are elements classified
they are grouped by there collums
No it is a metal. Not a semimetal. A semimeatal is in between metal and nonmetal.
A semimetal has the properties of both a metal and a nonmetal. They are also called metalloids.
Elements are classified as set out in the Periodic Table of the elements. It is NOT clear to what "three" you are referring.
Ok! So yea: The elements are classified by their properties by the reactivity and similarities between elements. I hope that helps...
most elements in the peiodic table are classified as metalloids
Elements
These elements are metals.
1) Elements can be classified by their state at room temperature; by whether they exist in nature; and by whether they are metals, nonmetals, or metalloids.
