Question

What is the ratio of sodium ions to chloride ions in one formula unit of sodium chloride with the chemical formula NaCl?

Answer 1

1:1

Step-by-step explanation:

NaCl is formed when sodium ion
`(Na^+)` combine with chloride ion
`(Cl^-)`
`Na^++Cl^-\rightarrow NaCL`

In this
`(Na^+)` 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
`(Cl^-)` 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
