Question

what is the name of this ionic compound? ca(no₂)₂ refer to a periodic table and a list of polyatomic ions. calcium nitrite monocalcium dinitrate calcium nitrate monocalcium dinitrite

Explanation:

• For ionic compounds, the naming rule is to name the cation first and then the anion.
• Here, the cation is \(Ca^{2 +}\) (calcium ion).
• The anion is \(NO_{2}^{-}\) (nitrite ion). According to the naming convention of ionic compounds (cation name + anion name), the name of \(Ca(NO_{2})_{2}\) is calcium nitrite.
• “Monocalcium dinitrate” is an incorrect naming as the prefixes “mono - ” and “di - ” are not used in the standard naming of simple ionic compounds (they are more relevant in covalent compound naming in some non - traditional cases which is not applicable here).
• “Calcium nitrate” would be for \(Ca(NO_{3})_{2}\) (where the anion is \(NO_{3}^{-}\) - nitrate ion).
• “Monocalcium dinitrite” is also an incorrect and non - standard naming for this ionic compound.

Answer:

calcium nitrite
