We present extensive non-local thermodynamic equilibrium (Non-LTE) calculations for a semi-empirical one dimensional (1D) solar chromospheric model based on the historically significant VAL C model. We report on the significant influence of nitrogen (N), oxygen (O), and sulfur (S) on the emergent hydrogen (H) continuum and line emission as computed with these elements in LTE and Non-LTE. Moreover, we present a model spectrum with 20 light and iron (Fe) group elements computed in Non-LTE. We compare this to an observed solar spectrum and to a photospheric model spectrum. We find that the agreement for this model with the data is less good than the original VAL C model especially in the UV. This may imply the need for changes in the chromospheric temperature structure or may point to general problems of static 1D chromospheric models.
