Main Question or Discussion Point
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?
It would have different chemical properties, yes. I'm not sure what you mean by 'stable' - atoms are quite stable. But if you excite (move up in energy) an electron with enough energy (the ionization potential), it may leave the atom altogether.but if only one electron did this and changed energy levels wouldnt it change the chemical properties of the atom? for instance, if one electron in helium moved up an energy level it wouldnt be stable anymore and it would have different chemical properties
No, not with normal temperatures. The states that normally correspond to heat is the kinetic energy of the atoms/molecules (their translational speed), their rotational energy levels, and their vibrational energy levels. (they have discrete levels just like the energy levels of the electrons).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 wouldnt 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?
