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 ...

A green laser pointer emits light with a wavelength of 532 nm. What is the energy of 1 photon of this laser pointer? As before, 6.02 x10-23 is represented as 6.02 x 10^-32 in the answers below. - 3.73 x 10^-19 A radio station broadcasts on a frequency of 92.5 kilocycles/s. What is the wavelength of this radiation in km? - 3.24 km A shell is defined by the principal quantum number, n, and contains all subshells. (True or false) - True A subshell is defined by the principal quantum number, ...

Quantum Mechanics History Planck ️Energy is discontinuous, quantum Einstein ️Light is both a wave and particle(Photoelectric effect) Bohr ️Bohr Model of Atom, electrons move in fixed orbits around nucleus, energy levels are quantized DeBroglie ️Matter is both a particle and a wave Heisenberg ️Uncertainty Principle:Can't know both location and velocity of a particle. Schrodinger ️Wave functions, orbitals, and quantum mechanical model

Quantum Physics Study Guide There have been two models of light. What are they and who first supported each? Particle: Newton and wave: Huygens (1600s) What determines the color with which a body glows? temperature What is Planck's equation? E=hf What does Planck's equation mean? Energy comes in discrete packets. Energy of a photon is proportional to its frequency. What does Planck's equation explain? Blackbody radiation problem and the photoelectric effect What is Planc...
