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-.

Calcium in its neutral state is denoted as Ca. Calcium in its oxidation state have +2 charge on it. The charged ion of calcium can be represented as Ca+2 .
