Whose idea was the modern periodic table?
Quick Answer
The modern periodic table is credited to Dmitri Mendeleev, who published his first version in 1869. He arranged the elements by recurring properties and predicted elements not yet discovered.
The Full Story
Dmitri Mendeleev, a Russian chemist, published a periodic classification of the elements in 1869. He organized elements by atomic weight and chemical behavior, leaving gaps where unknown elements belonged. Some of his predictions, including gallium and germanium, were later confirmed, strongly validating his approach. The table was later refined using atomic number, but Mendeleev’s framework remains central to chemistry. He is widely regarded as the father of the periodic table.
