- An atom that is considered a "good" electron needs to have an available energy level that is lower than the energy of a valence electron of a different atom. An atom that is considered a "poor" electron will have the valence electrons be at a higher energy than other atoms. Given this, consider rows 2 and 5 in the periodic table. Why should fluorine, in row 2, be more reactive than iodine, in row 5, while lithium, in row 2, is less reactive than rubidium, in row 5?arrow_forwardOne amazing and useful fact about nature is that different elements and molecules each have a unique pattern of energy levels available to their electrons.

- (50/100) 2. When a phosphorus atom is substituted for a silicon atom in a crystal, four of the phosphorus valence electrons form bonds with neighboring atoms and the remaining electron is much more loosely bound. You can model the electron as free to move through the crystal lattice. The phosphorus nucleus has one more positive charge than does the silicon nucleus, however, so the extra electron provided by the phosphorus atom is attracted to this single nuclear charge +e. The energy levels of the extra electron are similar to those of the electron in the Bohr hydrogen atom with two important exceptions. First, the Coulomb attraction between the electron and the positive charge on the phosphorus nucleus is reduced by a factor of 1/k from what it would be in free space, where k is the dielectric constant of the crystal. As a result, the orbit radii are greatly increased over those of the hydrogen atom. Second, the influence of the periodic electric potential of the lattice causes the…arrow_forwardWhat is a compound?
