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-.

In calcite, carbonate is chemically combined with calcium to form calcium carbonate (formula CaCO3). In dolomite, carbonate is chemically combined with calcium and the element magnesium (symbol Mg) to form calcium-magnesium carbonate (formula CaMg(CO3)2). In dolomite there is one magnesium atom for every calcium atom.oth are calcium-bearing carbonate minerals, meaning that they contain the chemical elements calcium (symbol Ca), carbon (symbol C) and oxygen (symbol O). Each carbon atom is combined with three oxygen atoms to form what is called carbonate (formula CO3).
