do all of the electrons in an atom have to move up or down an energy level or is it just the valence electrons or what? is there one photon released per electron and are they all the same wavelength?
kashiark said:but if only one electron did this and changed energy levels wouldn't it change the chemical properties of the atom? for instance, if one electron in helium moved up an energy level it wouldn't be stable anymore and it would have different chemical properties
kashiark said:ah i see ok ty and i meant chemically stable but i have another question; if you rub two objects together underwater they can keep putting out heat energy forever; once all of the electrons are in their lowest level wouldn't the heat energy stop being put out? or does the kinetic energy from moving the objects cause some of the electrons to move up an energy level?
