Document Summary

Three general topics: chemistry with aqueous solutions, structural and bonding properties of atoms and molecules, energetic aspects of chemical reactions. Evaluations: quizzes, tests: sept 28th, nov 9th (both at 7:00pm, final examination: dec see date to come (2. 5h, no makeup quiz/tests. Alkali metals have the smallest work functions takes less energy to eject its electrons. Quantum mechanics tells us that an atom has a discrete set of energy levels (only certain energies are allowed) Re = 2. 179 x 10-18 j rydberg energy negative. N = principal quantum number of hydrogen atom (1, 2, 3 - starts at 1) an is a consequence of the wave properties of matter. Transition energy is the energy of the photon emitted or absorbed (the difference between these energies) Transition frequency is given by dividing the transition energy by h. Colours we see are the ones that are not absorbed by the object.
