Au melting point
WebAug 14, 2024 · The melting points of metals, however, are difficult to predict based on the models presented thus far. Because Zn has a filled valence shell, it should not have a particularly high melting point, so a reasonable guess is C 6 (CH 3) 6 < Zn ~ RbI < Ge. The actual melting points are C 6 (CH 3) 6, 166°C; Zn, 419°C; RbI, 642°C; and Ge, 938°C ...

WebExperiments carried out with gold particles showed that below 10 nm the melting point decreases dramatically; a similar effect can also be expected for Cu, which belongs to the same group as Au [4]. In this case, at 20 nm the melting point is around 1300 K, i.e., the bulk melting temperature, while at 5 nm it is around 1000 K, 300 K less! http://www.chemicalelements.com/elements/au.html
