Dmitri Mendeleev played an important role in creating the periodic table.
Organizing Elements: In 1869, he sorted elements by their atomic mass, which is how heavy they are. He also grouped them based on their similar features.
Predicting Missing Elements: Mendeleev was smart enough to leave empty spaces for elements that hadn’t been found yet. He even guessed the properties of these missing elements. For instance, he predicted that germanium would be discovered before it actually was.
His work helped create the modern periodic table we use today!
