I love the periodic table and the fact you can click on each element for extra detail.

A little curious how one gets the atomic weights of transuranic elements, none of which (except maybe a little bit of plutonium and neptunium) exist in nature, and so cannot sensibly determine any natural proportion of isotopes.

For heavy transuranic elements(as well as for Tc) atomic weight correspond to the most stable isotope.
