NASA Ames Research Center shared SOFIA Stratospheric Observatory for Infrared Astronomy's video. Welcome back to California, SOFIA Stratospheric Observatory for Infrared Astronomy!! We're back at NASA's Armstrong Flight Research Center after six weeks observing the southern skies from Christchurch, New Zealand.
Report Abuse. Calcium is an element with an ion charge/oxidation number of 2+. Carbonate is a polyatomic ion with an ion charge of 2-. Since the two ion charges cancel out or equal zero, the formula would be CaCO3(the three is a subscript.) the Ca is the symbol for Calcium and the formula for carbonate is CO3.blah Â· 9 years ago.Thumbs up.arbonate is a polyatomic ion with an ion charge of 2-.

A calcium ion has 20 protons, the same as its atomic number. The number of electrons depends on the charge on the ion. For the most common calcium ion with a charge of +2, the â¦ number of electrons is 18; 20 - 18 = +2.The number of neutrons depends on the isotope that is ionized and is equal to the mass number of the isotope minus the atomic number of 20. calcium ion has 20 protons, the same as its atomic number.
