Demomitus's "Atomos" Model: Atoms are small, hard particles that are all made up of the same material, but are formed into different shapes and sizes
Aristotle's Model: He believed that matter was made up of only four elements (fire, air, water, and earth).
Model: Atoms are too small to see, uncuttable," and indestructible
Model: Atoms are made from a positively charged substance with negatively charged electrons
scattered about
Model: The nucleus is tiny compared to the atom as a whole, because the atom is mostly open space. Negatively
charged particles are scattered outside the nucleus at a distance.
Model: Electrons move in definite orbits around the nucleus. These orbits, or energy levels, are located at certain
distances from the nucleus.
Model: Electrons do not orbit the nucleus in neat planet-like orbits but move at high speeds in an electron cloud aroun
the nucleus.
