Alessandro Volta Built one of the first batteries, using copper, zinc, and brine-soaked cardboard.
John Dalton Proved through his experiments that all things are made of atoms.
J.J. Thomson Discovered that atoms are made of even smaller parts, called subatomic particles. He built a model of an atom that showed protons and electrons have an electric nature.
Earnest Rutherford Proved that an atom has a nucleus. He also showed that the majority of each atom is just empty space. His model of an atom also showed electrons spaced out around a central cluster.
Niels Bohr Built a model of an atom, showing that electrons move in a circular motion around the nucleus. His model is still used today to help students understand what an atom probably looks like.
Earnest Rutherford and James Chadwick Later discovered that there are also neutral particles inside an atom. They called these particles neutrons.
Robert Boyle He has often been called the “father of modern chemistry,” because of his discoveries about matter, elements, and compounds.
Dmitri Mendeleev Organized the known elements into what is now known as the Periodic Table.
