Deducing the ions in a polyatomic ionic compound from its empirical formula calculator

  • The third column is headed by B, but usually the only atom of interest in high school is Al and its charge of +3. An example ionic compound might be AlCl 3. The other elements in this column exhibit such complex patterns of behavior that they tend to get ignored in high school chemistry. That does it (for the moment) for the positives, guys and ...
  • The reliability of the experiment was limited to the method which the bounce height was measured. Since the tennis ball reached its apex height on the rebound at a high speed, it was difficult to measure with adequate precision with sight alone. Parallax errors were difficult to avoid as the bounce height was slightly different for each trial.
