The name of the compound represented by the formula NaI is sodium iodide.
Sodium iodide is a compound and that is its name.
Sodium iodide, like all sodium compounds, is ionic.
Aqueous lead nitrate plus aqueous sodium iodide produce solid lead iodide and aqueous sodium nitrate.

Pb(NO3)2(aq) + 2NaI(aq) → PbI2(s) + 2NaNO3(aq) Aqueous lead II nitrate reacts with aqueous sodium iodide to form solid lead II iodide precipitate and aqueous sodium nitrate.
-288 kJ/mol
Pb(NO3)2(aq)+2NaI(aq)=2NaNO3(aq)+PbI2(s)
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
When aqueous solutions of silver nitrate and sodium iodide [note correct spelling] are mixed, silver iodide solid precipitates from the mixture.
