36 views3 pages
Document Summary
Frequency= indicates how many wave peaks pass a certain point per given time period. Speed= how fast one particular wave travels, through a space. An atom is said to be in an excited state when it has excess energy. When an atom is in the lowest possible energy state; it in the ground state. The energy of the photon corresponds to the change in energy that the atom experiences. All hydrogen atoms have the same set of quantized levels. Quantized energy levels result in emission of only certain colors. Has to go from one state to another; no in between. The energy levels of all atoms are quantized. Electron jumps between levels by absorbing or emitting a photon of a particular wavelength. Involves orbitals= regions where there is a high probability of finding an electron. One can predict the probability of finding the electron at given. An orbital"s size is the sphere that contains 90% of the total electron probability.
