... Many of these planetesimals had metallic iron cores and during growth of the Earth this metal re-equilibrated with the Earth's silicate mantle, extracting siderophile (`iron-loving') elements into the Earth's iron-rich core. ... Chemical signature of core formation Growth of the Earth from planetary embryos and planetesimals resulted in the substantial partitioning of siderophile elements into the metallic core, leaving lithophile elements behind in the silicate mantle. ... REE, rare-earth elements....

... The "Mulliken" AMMs up to the fourth order were calculated within the scheme developed by Saunders et al. [13] using the B3LYP, Perdew-Wang (PW91), and Perdew-BurkeErnzerhof (PBE) functionals with the 6-21G** basis set (for shortness, noted below basis set 3 or BS3) for all ALPOs, while the ATN and ATO structures were also considered at other levels as STO-3G (BS1), 3-21G (BS2), and 8-511G*(Al)/8-521G*(P)/8411G*(O) (BS4) for comparison. ...
