How are Compounds Formed? S-cool, the revision website

The formation of compounds Most elements form compounds. For example: A reaction between sodium and chlorine gives the compound sodium chloride (salt) quite readily. The noble gases do not usually form compounds. They are different from other elements, since their atoms are described as stable or unreactive. They are stable because their outer electron shell is full.

What is compound? - Definition from WhatIs

1) In chemistry, a compound is a substance that results from a combination of two or more different chemical element s, in such a way that the atom s of the different elements are held together by chemical bonds that are difficult to break. These bonds form as a result of the sharing or exchange of electron s among the atoms. The smallest unbreakable unit of a compound is called a molecule .
