Modern methods of teaching chemistry course are considered using an example of algorithms. It is shown that the algorithms can be implemented in the process of studying chemistry when creating formulas and equations, solving and independently preparing experimental and theoretical tasks of different types, in the description of properties of elements and complex substances when establishing a possibility of chemical reactions. Special attention is paid to quantity laws of chemistry (equivalent), the structure of the atom (Mendeleev Periodical system of elements), algorithms of solution of common problems by the equations of redox and other reactions.
