Document Summary
E- exhibit properties of both waves + particles. Back to the analogy: rider + elephant obey the laws of classical, newtonian physics, horsefly is where it gets weird. Because the uncertainty of the position of a particle depends on the wavelength of the particle in question in this analogy, the horsefly is small enough to have significant wave-like properties. When photons of nrg are absorbed by e-, the energy of the electrons is. Different atoms emit/absorb photons with different levels of energy: evidenced by absorption spectra which have finite lines, thus, from substance to substance, the different energies of an atoms electrons can vary. Periodic variation of the properties of the elements. Law of chemical periodicity the properties of the elements vary periodically with their atomic #s. Elements w/ similar properties are arranged in groups (vertical) on the periodic table. Atomic radius increases as you go to the left and down the periodic table.
