Na + ( a sodium ion )
A cation
bonds with
SO4 2- ( the polyatomic ion sulfate )
an anion
to form
Na2 SO4
The ionic compound sodium sulfate
4Na(s) + O2(g) → 2Na2O(s)
magnesium
Na+O-2
NH4I + NaOH -> NH4+ + I- + Na+ + OH- -> NH3 + H2O +I- + Na+
The ionic formula is Na+ Cl-
Na^(+) + Cl^(-) = NaCl(s)
Na+ CN- = NaCN
NaHCO3 with Na+ and HCO3- ions

NH4I + NaOH -> NH4+ + I- + Na+ + OH- -> NH3 + H2O +I- + Na+
The ionic formula is Na+ Cl-
Na^(+) + Cl^(-) = NaCl(s)
The elements are sodium, Na, and chlorine, Cl. The bond is ionic. The ionic formula is Na+ Cl-
NaBr would be a formula unit as all sodium (Na) compounds are ionic.
Na+1 NO3- => Na(NO3)
Na+ CN- = NaCN
