What is most of the matter around you is in the form of (elements, compounds)?
Most elements are not stable in their elemental form. In order to become stable, they chemically combine with atoms of other elements through covalent and ionic bonding. Covalent bonding involves sharing electrons, usually between nonmetals, and ionic bonding involves the transfer of electrons from one atom to another, primarily between metals and nonmetals or metals and polyatomic ions.
