- Hello I'm Democritus, and I believe atoms are uniform, solid, hard, incompressible, and indestructible and that they move in infinite numbers through empty space until stopped.
- My name is John Dalton, and I believe atomic theory proposes that all matter is composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
- Hello I'm Michael Faraday, I discovered the idea that atoms have an electrical component. I placed two opposite electrodes in a solution of water containing a dissolved compound.
- I am JJ Thomson and I experiment with cathode ray tubes showing that all atoms contain tiny negatively charged subatomic particles and electrons electrons.
- Hello I am Ernest Rutherford and I found that the atom is mostly empty space, with nearly all of its mass concentrated in a tiny central nucleus.
- Hello, I am James Chadwick and I discovered the neutron. A neutron is a particle with no electric charge that, along with positively charged protons, makes up an atom's nucleus. Bombarding elements with neutrons can lead to an enormous amount of energy.
