In November 2016 all artificial chemical elements were

recognised and baptised.

As of 2015, there are 23 man made elements. Technetium (atomic

no 43) is the only man-made element that comes before uranium (92),

the heaviest natural element.

Scientists have made 22 transuranium elements.

There are a further 4 - Ununtrium (113), Ununpentium (115),

Ununseptium (117) and Ununoctium (118) - whose existence has been

claimed. However, these are not yet recognised by International

Union of Pure and Applied Chemistry (IUPAC).
