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 chemical formula is a concise list of the elements in a compound and the ratios of these elements. To better understand what a chemical formula means, we must consider how an ionic compound is constructed from its ions.alcium ions have a charge of 2+, while nitrate ions have a charge of 1â. We will need two nitrate ions to balance the charge on each calcium ion. The formula for nitrate must be enclosed in parentheses. Thus, we write Ca(NO3)2 as the formula for this ionic compound.
