For chemistry students and teachers: The tabular chart on the right is arranged by Atomic mass (weight).

The lightest chemical element is Hydrogen and the heaviest is Hassium.

The unity for atomic mass is gram per mol.

Please note that the elements do not show their natural relation towards each other as in the Periodic system. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals.

Dave, your head post doesn't mention all the dark matter in the universe.

(My opinion is that physicists made up dark matter because the their theories couldn't explain observations)
