Understanding the Atom Finding Numbers of Protons, Neutrons, Electrons and Key 10. Complete Model of Atom Graphic Organizer and Key 7. Atomic Model of Matter Worksheet and key 5. I would encourage you to explore further. The Atomic Model of Matter Graphic Organizer and key 4. h E ( 1 n l o w 2 1 n h i g h 2) 13.6 eV. Bohr explained the hydrogen spectrum in terms of electrons absorbing and emitting photons to change energy levels, where the photon energy is. looking for relationships in a meaningful way. Bohrs model calculated the following energies for an electron in the shell, n. We can, however, say that the more electrons there are in an atom, the greater the variety of photon energies there will be so this may be a link worth exploringĪs I say, you are asking a great question. as it switches from one energy level to another, then it emits / absorbs photons. The lines in the sodium lamp are broadened by collisions. Due to the very different emission spectra of these elements, they emit light of different colors. Many street lights use bulbs that contain sodium or mercury vapor. This is because the electron can exist in many energy levels. 2: The emission spectra of sodium and mercury. Hydrogen, for example, although the simplest atom, has a whole range of photon energies that it emits. The value of the energies of photons does depend on the available energy levels in the atom. Now, the energy of the photon emitted from any element does not depend on the number of electrons in the atom. OK: I would say that the periodic table tells us about the number of protons in an element and, therefore the number of electrons too. Here is my answer, but I would encourage you to explore this and similar questions further.
