Atoms are joined together by chemical bonds, which involve the electrons found around the nucleus of the atom. Covalent bonds and ionic bonds are two types of chemical bond.

During a chemical reaction, reactants are changed into products. Chemical symbols and formulae are used to represent substances in symbol equations. Molecular formulas show the number of each type of atom in a molecule, while displayed formulas show the atoms and bonds in a molecule.



Atoms have a small central nucleus surrounded by even smaller particles called electrons. The nucleus is positively charged,
