How do you know if a compound is binary or ternary?

Answer 1

An element is a pure substance it can not be broken up into anything else.

A compound is two or more pure substances joined together chemically, such that they can not be separated physically - a new substance. However this substance can be converted chemically back into its component bits.

A mixture is two or more substances that are mixed up but not joined together, such that they can be separated physically.

There is also the a "solution" which is like a mixture but where the mixing is happening at a molecular level, it is possible to separate the components physically, but not easily.

Answer 2

a binary compound that contain exactly 2 different element. Example NaCl ( sodium chloride), NaF ( sodium fluoride), MgO ( magnesium oxide)

Answer 3

A binary compound contains only two different elements. Sodium Chloride, common Salt, is a binary compound because it contains only the elements Sodium and Chlorine.

Answer 4

This is determined by chemical analysis.
