Answer:
1:1
Explanation:
NaCl is formed when sodium ion [tex](Na^+)[/tex] combine with chloride ion [tex](Cl^-)[/tex] [tex]Na^++Cl^-\rightarrow NaCL[/tex]
In this [tex](Na^+)[/tex] is a cation which is formed by losing an electron from sodium element .Sodium loses one electron to become stable because it has one extra valence electron
And [tex](Cl^-)[/tex] is a anion which is formed by gaining one electron to become stable
So in NaCl there is 1 sodium and and 1 chloride ion so ratio will be 1:1
