The chemical properties of the baryonic components of galaxies encode crucial information about the formation and evolution of the structure in the Universe.  In this work, we study the chemical evolution of galaxies since early cosmic times until the present by using state-of-the-art numerical cosmological simulations. We analyse the evolution of nuclei abundances of galaxies inhabiting halos of different masses, considering physical models corresponding to different feedback scenarios.  We pay particular attention to the connection between the chemical properties of different baryonic phases in galaxies (e.g. cold gas, hot gas, stellar component) and try to determine the existence of scaling relations between them which can be compared with observational data.
