A method of calculating degrees of ionization and excitation of hydrogen atoms in the impulse phase of flares is given, based on simultaneous solution of the radiative transfer, statistical equilibrium and particle number conservation equations at a given moment of time. To test the convergence of the method in the framework of the simple two-level continuum model of the atom, calculations are made of distributions in depth of degree of ionization and excitation of the second level for the model of an elementary flare burst (EFB), which is the result of a gas dynamic response to electron beam injection with an initial flow on the upper boundary F(0) and a spectral index gamma. Convergence is reached in less than 20 - 25 iterations. Preliminary results are obtained on the dominant effect of the beam's electrons on an increase in the degree of ionization of an EFB hydrogen plasma in the lower chromosphere. A more realistic model of the atom should be introduced and the effect of other EFB plasma components taken into account before final conclusions are drawn.
