Answer : The ionic compound formula is [tex]NaF[/tex].
Explanation :
Ionic formula : An ionic formula consist of positively and negatively charged ions. In an ionic formula, the charge should be balanced. That means the total positive charge is equal to the total negative charge.
Naming ionic compound with two elements :
- First, identify the cation and anion.
- Balance the charges of cation and anion.
- In the ionic formula, write the cation first, using subscripts from the charge balance and then write the anion.
In the given ions, [tex]Na^{1+}[/tex] is the cation and [tex]F^{1-}[/tex] is an anion.
The charge on sodium ion is (+1) and on fluoride ion is (-1). The charges of cation and anion is balanced.
Therefore, the ionic compound formula is [tex]NaF[/tex].
