During formation of Ca(NO3)2, Calcium donates two electrons and gets converted to Ca2+, while two ammonium ions gain one electron each and get converted to nitrate ion (NO3–).

Calcium nitrate is a calcium nitrate salt that contains calcium, nitrogen, and oxygen. Calcium nitrate is a granular solid that is white or whitish-grey in colour and absorbs moisture from the air. It is commonly found as the tetra hydrate compound Ca(NO3)2.4H2O.
