- I am Democritus! and I found out that everything in our world is made of tiny particles surrounded by empty space.
- hi! I am atomos!
- I am John Dalton and I showed that common substances always broke down into the same elements in the same proportions. I concluded that various compounds were combinations of atoms of different elements, each of a particular size and mass.
- I'm carbon dioxide and I have a combination of several atoms in me!
- I am J.J. Thompson and I discovered the electron. I showed atoms as uniformly packed spheres of positive matter filled with negatively charged electrons.
- wow I have a lot of green positive matter and red negatively charged electrons
- I am Ernest Rutherford and I did an experiment where I shooted small,positively charged alpha particles at a sheet of gold. I concluded that atoms consisted largely of empty space with just a few electrons,while most of the mass was concentrated in the center,which he called the nucleus.
- i am the positively charged nucleus
- i am an electron
- I am Niels Bohr and I expand on Rutherford's nuclear model. I stipulated that electrons orbit the nucleus at fixed energies and distances., able to jump from one level to another, but not to exist in the space between.
- I am a Bohr Model.
- I am Werner Heisenberg and I showed that it was impossible to determine both the exact position and speed of electrons as they moved around the atom.
- electrons move in different ways around me.
