The ATLAS collaboration has carried out several measurements of particle production properties and correlations at different pp collisions centre-of-mass energies. The production properties of mesons and baryons at sqrt(s)=7 TeV are presented and compared to predictions. The effects of space-time geometry in the hadronization phase has been studied in the context of Bose-Einstein correlations between charged particles, for determining the size and shape of the source from which particles are emitted and for interpreting of quark confinement effects. Bose-Einstein correlation parameters are investigated in p-p collisions at 900 GeV and 7 TeV, up to very high charged-particle multiplicities. In addition, particle distributions sensitive to the underlying event in proton-proton collisions have also been measured at 7 TeV centre-of-mass energy in different final-state processes.
