The metal opacity has an important influence on the emergent flux of hot stars in the EUV and X-ray range of the spectrum. The commonly used NLTE model atmospheres for spectral analysis of these stars consider only H, He, C, N, and O and thus, are not well suited for a reliable calculation of these fluxes. Moreover, the effect of the metal resonance lines on the temperature structure of the outer atmosphere, especially of the line forming region, can change the theoretical line profiles of H, He etc. which may result in different photospheric parameters. NLTE model atmospheres are presented which consider all elements from hydrogen to calcium for the interpretation of EUV and X-ray spectra.
