Nov 21, 2023 · The chemical formula of the ammonium cation is {eq}{\rm{NH}}_{\rm{4}}^{\rm{ + }} {/eq} as it consists of a nitrogen atom attached to four hydrogen atoms.
The \(\ce{NH4}\) in the formula represents the ammonium ion, \(\ce{NH4^{+}}\), which indicates that this compound is ionic. Both oxygen and fluorine are nonmetals. Therefore, \(\ce{OF2}\) is not ionic.
What is Ammonium Ion? “Ammonium is a polyatomic cation with a chemical formula NH 4 +. A cation is an electron-deficient species that carries a positive charge.
