Atomic diffusion in stars can create systematic trends of surface abundances with evolutionary stage. Globular clusters offer useful laboratories to put observational constraints on this theory as one needs to compare abundances in unevolved andKeywords: Globular clusters: individual: NGC 6752; Stars: abundances; Stars: atmosphere; Stars:fundamental parameters; Techniques: spectroscopic; Astrophysics; Calcium; Chemical elements; Diffusion in solids; Lithium; Mixing; Scandium; Stars Globular clusters: individual: NGC 6752; Stars: abundances; Stars: atmospheres; Stars: fundamental parameters; Techniques: spectroscopicAtomic diffusion and mixing in old stars: IV.
