Elements with low melting point
WebThe low melting points for the light to middle lanthanides are thought to be due to a 4f electron contribution to the bonding, which is a maximum at cerium and decreases with increasing atomic number to about zero at … WebSep 3, 2024 · We expect C6(CH3)6 to have the lowest melting point and Ge to have the highest melting point, with RbI somewhere in between. 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 …
