alternative method help

What can be an alternative method to make sodium chloride which can have an impact atom economy? the first one i used was HCl + NaOH- NaCl + H20. So do they mean changing some substances if so what can be the substitues? thanks for any help

Na +

\frac{1}{2}

Cl₂ -> NaCl
This reaction has 100% atom economy, while your original only has 76%

Na + HCl would be another, which would come out somewhere in between the 100% method and your one.

not a very 'safe' reaction though ...

There has to be some compromise between atom economy, expense and safety. Mine also wasn't safe, using pure Cl₂gas. The question was purely about atom economy though, so I answered with the reaction with the highest atom economy.
