deciding bond type from physical properties

As an example: You would expect stronger metallic bonding in aluminium than in magnesium, because aluminium has 3 electrons to delocalise into the "sea of electrons" rather than magnesium's 2.The boiling points reflect this: Al 2470°C, Mg 1110°C. However, aluminium's melting point is only 10°C higher than magnesium's: Al 660°C, Mg 650°C.
