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 30, zinc, Zn, is a bluish-white metal.  Zinc is a biologically
essential trace element for the growth of animals, a zinc deficiency
requires 5¯% more food to gain the same weight.  Zinc oxide has unusual
electrical, thermal, optical, and solid-state properties. An alloy of
zinc-aluminum exhibits superplasticity.  Zinc is used to galvanize
other metals such as iron to prevent corrosion.  Zn is superconductive
below 0.85 K.
