   Calcium ions have a charge of 2+, while nitrate ions have a charge of 1−. We will need two nitrate ions to balance the charge on each calcium ion. The formula for nitrate must be enclosed in parentheses.

   25 wrz 2022 · If you know the name of a binary ionic compound, you can write its chemical formula. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge. Because the overall compound must be electrically neutral, decide how many of each ion is needed in order for the positive and negative charges to cancel each other out.

   This formula indicates that there are three calcium ions (Ca 2+) for every two phosphate (PO 4 3−) (PO 4 3−) groups. The PO 4 3− PO 4 3− groups are discrete units, each consisting of one phosphorus atom and four oxygen atoms, and having an overall charge of 3−.

   So you do not need to state the number of cations and anions, you only need to state what they are (and what their charge is). You then figure the formula based on the lowest whole number ratio of cations to anions that produces a neutral formula. We will start with binary ionic, which are between monatomic anions and cations.

   Writing ionic formulas requires knowing the charges of ions in the compound. In general, the charge of the positive ion is written on the negative ion and the charge of the negative ion is written on the positive ion creating a cross-over. For example, if the Calcium ion is +2 and Chloride ion is -1, then Calcium Chloride is written CaCl2.
