  • isaac newton

    isaac newton
    proposed a mechanical universe with small solid masses in motion
  • john dalton

    john dalton
    argued about the atomic theory originally proposed by the greeks
  • jj thomson

    jj thomson
    jj thomson proposed that the atom had a plum pudding structure
  • the quantum idea

    the quantum idea
    planck quantum idea was developed as a way of explaining black body radiation and the associated ultraviolet catastrophe.
  • the geiger marsden experiment

    the geiger marsden experiment
    involiving a beam of alpha particles fired at a thin foil of gold to measure the deflection as the alpha particles interacted with the plum pudding gold atoms
  • the bohr atom

    the bohr atom
    constructed a model of the atom that had small,light, fast,particle like,negatively charged electrons orbiting a small massive positively charged nucleus.
  • spectroscopy and quantum numbers

    spectroscopy and quantum numbers
    niels bohr,sommerfield,,stoner and pauli devised the quantum numbers from empirical spectroscopic evidence
  • lewis theory

    lewis theory
    lewis proposed the two electron chemical bond later named the covalent bond by langmuir.
  • pauling's five rules crystal structure

    pauling's five rules crystal structure
    the crystal structure of an ionic compound.
  • pauling's electronegativity

    pauling's electronegativity
    linus pauling used empirical heat of reaction data to introduce the elemental property of electronegativity which he defined as:the desire of an atom to attract electrons to itself
  • hellmann feynman theorem

    hellmann feynman theorem
    the hellman feynman theorem states that once the spatial distribution of electrons has been determined by solving the schrodinger equation all the forces in the system can be calculated using classical electrostatics
  • van arkel-ketelaar triangle

    van arkel-ketelaar triangle
    deals with 3 extreme types of bonding metallic ionic and covalent.
  • valence shell electron pair repulsion(VSEPR)

    valence shell electron pair repulsion(VSEPR)
    states that electron pairs repel each other.
  • frontier molecular orbital theory

    frontier molecular orbital theory
    was developed in the 1960's by kenichi fukui who recognized that chemical reactivity can be expalined in terms of interacting highest occupied MO'S lowest unoccupied MO'S and single occupied MO'S
  • molecular mechanics and molecular dynamics

    molecular mechanics and molecular dynamics
    this method treats a molecular as a collection of particles held together by elastic or simple harmonic forces.
