Document Summary
Consequences of having more energy in the earth-system: more intense weather, more and stronger hurricanes and thunderstorms, disruptions to global weather patterns, warmer oceans, warmer arctic. The allowed electron energies are very specific to the kind of atom (element: amount of energy in the electron"s orbit is related to the average distance of the electron from the nucleus. If we add enough energy, the electron escapes altogether from the atom. Energy levels of a hydrogen atom: different allowed orbits or energy levels in a hydrogen atom. Electrons can move between states by exchanging energy by emitting or absorbing a photon. Ground state = lowest energy an electron can have in that type of atom. Then first excited state, second excited state, third excited state, etc. Electrons always want to go to lowest energy state (ground state) 23. light through cloud of gas through prism.
