... accelerating charges. Since the hydrogen atom only radiates when its electron "drops" from one excited state to a less energetic state, Bohr postulated that "the hydrogen electron does NOT radiate energy when it is in one of its bound states (allowed by n). It only does so when "dropping" from a hig ...

... SOLUTION: (a) ClO4- is perchlorate; Fe must have a 2+ charge since there are 2 ClO4- ions. This is iron(II) perchlorate. (b) The anion sulfite is SO32-; therefore you need 2 Na+ for each sulfite. The formula is Na2SO3. (c) The ionic compound is barium hydroxide. When water is included in the formula ...
