The chemi-ionization processes in atom - Rydberg atom collisions. as well as the corresponding chemi-recombination processes. are considered as factors of influence on the atom exited-state populations in weakly ionized layers of stellar atmospheres. The presented results are related to the photospheres of the Sun and some M red dwarfs. https://macorners.shop/product-category/heart-puzzle-keychain-gift-box/
