Radiodating isotopes

This crystal system is shared by some other metals, such as lead and copper; the size of a unit cell of aluminium is comparable to that of those.

It reacts with water or dilute acids to give methane.

The acetylide, Al, is made by passing acetylene over heated aluminium.

It is essentially the only isotope representing the element on Earth, which makes aluminium a mononuclidic element and practically equates its standard atomic weight to that of the isotope.
