Chemists were able to quantitatively explain the behavior of the elements, and to predict the existence of printable periodic table of elements yet undiscovered ones.
Progressing through a group from lightest element to heaviest element, the outer-shell electrons (those most readily accessible for participation in chemical reactions) are all in the same type of orbital, with periodic table a similar shape, but with increasingly higher energy and average distance from the nucleus.
periodic table of element Mendeleev was later vindicated by the discovery of the electronic structure of the elements in the late 19th and early 20th century.

The Solar System was created from the remnants of previous stellar systems that went supernova, and is hence, relative to the rest of the universe, richer in heavier elements.
The six very rare, highly radioactive elements (polonium, astatine, francium, radium, actinium and protactinium) have such low natural abundances that they are not included or their natural adundances are not known as they are so low.
See sea water for abundance of elements in the ocean, but note that that list is by mass - a list by molarity would look very different, especially as regards the first 4 elements; specifically, hydrogen would comprise well over half of such a list.
