16.5: Carbon and Silicon: Network Atomic Solids

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
