Dmitri Mendeleev was a Russian inventor and chemist who developed the periodic law.
He used this law to correct the properties of a few already discovered elements and he also predicted the properties of several elements that at the time hadn’t been discovered.
Mendeleev also created a periodic table and arranged the elements he knew of at the time in order of relative atomic mass.
Henry Moseley was an English physicist who studied chemistry and physics.
Mendeleev’s periodic table was almost correct, but it needed a very important modification to make it the modern periodic table we know today. Moseley introduced using the atomic number not atomic mass to organise the elements in 1913.
After conducting multiple different experiments, he proved
