The existence of two types of gluons in QCD, the color neutral neurons and colored chromons, implies that the chromons can be the constituent of hadrons. This generalizes the quark model to the quark and chromon model. We discuss the glueballquarkonium mixing in QCD based on the quark and chromon model. We present the neumerical analysis of glueball-quarkonium mixing below 2 GeV in 0++, 2++, and 0-+ channels, and predict the relative branching ratios of the radiative decay of to the physical states.
