In general, when is electromagnetic radiation produced? - ANSWERWhen charged particles move. According to the Bohr model of the atom, the single electron of a hydrogen atom circles the nucleus..how? - ANSWERIn specific, allowed orbits. All orbitals within the p sublevel.. - ANSWERare at the same energy and have the same shape What is true about microwave ovens? - ANSWERMicrowave ovens heat food by rotating water molecules Visible light, X rays, infrared radiation, and radio waves all have the same what? - ANSWERSpeed The wave model of light explains what? - ANSWERThe frequency of lights, the continuous spectrum, interference, and reflection (does NOT explain spectral lines). Both copper and chromium appear to break the pattern in the order of filling the 3d and 4s orbitals. This change in pattern is expressed by: - ANSWERA reduction in the number of electrons in the 4s orbital and an increase in the 3d orbital The wave-particle duality of light means that.. - ANSWERLight acts as both a wave and a particle The number of electrons in the highest occupied energy level of the argon atom is.. - ANSWER8 Which of the following elements highest occupied energy level is the 5th energy level?
