(1) Ar is your answer. Argon is a noble gas, which is stable in its standard valence electron configuration because it already completed its valence shell following the octet rule.
Explanation:

The precipitate of reaction that occurs when silver nitrate solution is mixed with sodium chloride solution is of silver chloride (AgCI).
The chemical equation for this precipitation reaction is as following:
AgNO3(aq) + NaCl(aq) --> AgCl(s) [precipitate]+NaNO3(aq)
- Silver Chloride is a chemical compound which is poorly soluble in water because the chemical bond between Ag+ and Cl is very strong as the two ions are nearly the same size and have similar electronic densities.
- If the chemical bond is strong, it is difficult for water molecules to break this bond to surround the individual ions, thus solubility will decrease.
