What I especially want to emphasize are any superlatives of the
elements, i.e. , the chemical properties and the nuclear properties,
each element has which are unique, aside from the fact of the
uniqueness of atomic number. Please point out any superlatives which I
have overlooked. There are mistakes in these descriptions please notify
me of the mistakes.

Element 31, gallium, Ga, is a soft, silvery-white metal.  Gallium is
unusual for its low melting point, it expands upon solidification one
of the few metals that expands as it freezes, as do nonmetals and most
gases.  Gallium, cesium, and mercury are the only three metals that are
liquid at room temperature.  Gallium is unique in that it has the
largest liquid range 303K to 2693K  of any element.  Main use of
gallium is the electronic industry in such compounds as GaAs
semiconductors; gallium transistors. Gallium is used for doping in
solid-state devices.
