Earnest Rutherford
Earnest Rutherford discovered empty space. He was the only one credited with this discovery. Through many tests, Rutherford realized that between the nucleus of an atom and the electrons and protons orbit rings is emptiness. This is important because it helps us properly construct an accurate model of the atom. -
Niels Bohr
Niels Bohr discovered fixed energy and the planetary model. Both Niels and Planck were credited with this discovery. This discovery shows that atoms are organized like solar systems. The electrons orbit the protons and neutrons, which is like planets orbiting the sun. This is important because it shows how the electrons work around the protons and neutrons. -
James Chadwick
James Chadwick discovered the neutron. The neutron, James discovered, is an uncharged particle within the nucleus of an atom. This is important because it tells us what makes up an atom.
