In the year 1649, scientist Hennig Brand isolated phosphorus by distilling human urine thus creating the trend of isolating elements which made more scientists isolate more elements.
In the year 1789, Antoine-Laurent de Lavoisier published one of the earliest chemistry books known to man, the book contained a list of 33 elements.
In the year of 1817, a German scientist named Johann Doberenier came up with a law of "triads" after noticing that there were trends within certain groups of elements.
In the year 1864, a chemist named Julius Lothar Meyer created the first periodic table but was not praised for it as it was too weak for the brains of the geniuses, as it only contained 28 elements, did not leave room for undiscovered elements, and was arranged by valence instead of by atomic mass, how disgraceful.
After fixing the mistakes that Lothar made, in 1869 the famous chemist Dimitri Mandaleev created the first proper periodic table that was the foundation to the one we use today.
In the year 1918, a British physicist named Henry Mosely experimentally confirmed Bohr's model of the atom.
