    • Atoms are miniscule quantity of matter that can't be destroyed differ size, shape, & temp.
    • "The universe is composed of two elements ; the atoms and they exist and move."
    • Atoms Appearane: Solid- Small,pointy atoms; Liquids- Large, round atoms; Oils- Are made of very small atoms.

  • Dalton- - Elements consist of tiny particles called atoms, states elements are one of a kind.- Meteorology led him to view atomism, then calculated atomic weights, came up with the Atomic Theory.

  • Bohr:- Bohr discovered that electrons traveling in orbits around nucleus are chemical properties being determined by how many electrons are in the outer orbit.- Used the metohd of Planck Quantam- Atom looked like a cookie.

  • Heisenburg & Schrodinger: - Developed the Uncertainty Principle; impossible to know exact momentum of an electron.- He used an equation, The Schrodinger Equation - Looked like an periodic table
