what kinds of evidence can you use to determine if a chemical reaction has occurred?

Electrons on more metallic elements are lost and those electrons are gained by non-metallic elements to form ionic bonds. Another way is for the electrons to be shared, rather than exchanged. Sharing of electrons forms a covalent bond.

Change in color, change in temperature, light, formation of a precipitate (if the reactants are solutions).
