CLEP Chemistry Latest Update Graded A John Dalton Proposed that matter is composed of atoms; these atoms have different identities called elements, which combine to form compounds; measured masses of reactants and products. J.J. Thompson Observed deflection of particles in a cathode ray tube; proposed that atoms are composed of positive and negative charges; developed the plum pudding model of the atom Robert Millikan Calculated the charge-to-mass ratio of electrons using oil drops falling in ...

Atomic Number - ️️number of protons found in that atom; low number; (Z) Mass Number - ️️Protons + Neutrons; high number; (A) Atomic Mass - ️️relative mass of that atom compared to the mass of a carbon-12 atom (which is set at 12.00); measured in amu; 1 amu = - ️️1.66x10^-24 Atomic Weight - ️️weight (g) of one mole (mol) of a given element (g/mol); the weighted average of all the masses (not the weights) of an element, weighted according to the natural abundance of...

Schrodinger (1925) Continued upon Bohr's findings to determine where electrons are typically found. Heisenberg (1927) Created the heisenberg uncertainty principle because you never can predict where the electron is. (Breaking Bad) De Broglie (1924) Electrons act like waves around the atom. Niels Bohr (Bohrbit) (1913) Electrons can orbit the nucleus in certain special orbits at different energy levels around the nucleus. Earnest Rutherford (foil) (1910) Fired beam of alpha particles ...

Quantum Mechanics Already Graded A+ Max Planck : German physicist who solved the problem of why different wave lengths are emitted at different temperatures- proposed that the energy absorbed or emitted by an object could only occur in "pieces"- which he called quantum Wener Heisenberg : German theoretical physicist- published his theory on quantum mechanics when he was 23- concluded that it is impossible to make a measurement on an object without disturbing the object Albert...
