Hint for Writing the Formula for Calcium carbonate

Calcium carbonate! This is a nice one. We have a metal (Calcium) and a polyatomic ion (when you see a name ending in ate it is likely an ion).
  • Write the element symbol and ionic charge for Calcium .
  • Look up the name and charge for carbonate on the Common Ion Table
  • Balance the charges so the total charge on the compound is zero. The charges balance out for this one which is very nice, indeed.
