Abstract: The study was aimed to analyze the relationship between physicochemical properties of metals and their crustal abundances. The results showed that 10 out of 21 physicochemical properties of metals were significantly related with the logarithm of their crustal abundances, ranking in the following order according to the size of the correlation coefficient (R2): covalent-bonding index (Xm2r), atom density (ρ), atomic number (AN), atom weight (AW), efficient nuclear charges (Z*), electronegativity (Xm), softness index (σp), electron affinities (EA), polarization force (Z*2/r) and electrochemical potential (ΔE0). The relationship was further proved by the set pair analysis. It was indicated that the physicochemical properties of metals were closely related with their crustal abundances. The study is helpful to know more about the Earth evolution and elements and to make best use of the rock and mineral resources.
