Final answer:
Dmitri Mendeleev, a Russian chemist, is renowned for the independent discovery of the periodic table, which he first published in 1869 and famously predicted the existence of then-unknown elements.
Step-by-step explanation:
The scientist who is best remembered for his independent discovery of the periodic system is the Russian chemist Dmitri Mendeleev. He first published his periodic table in the year 1869. Mendeleev's arrangement of the elements was based on their increasing atomic mass and the periodic nature of their properties. Unlike others, Mendeleev did not assume that all elements had been discovered, leaving gaps in his table for elements that were yet to be found. This showed great foresight as later discoveries of elements like gallium and germanium fit perfectly into the spaces he predicted, with properties he anticipated, confirming the utility of his periodic table.
