The temperature dependence of the particle concentration in hydrogen and hydrogen-helium models of stars photospheres in the temperature region $(5\cdot 10^3\div 5\cdot 10^4 )$\,K at the densities of $(10^{-7}\div 10^{-5})$ g$/$cm$^3$ is investigated. A self-consistent calculation of the partition function of the hydrogen atom is performed. A non-monotonous dependence of the screening parameter and the concentration of ${\rm H}^-$-ions is established.
