In the compound NaF2, sodium typically has an oxidation state of +1, and fluorine has an oxidation state of -1. When combined in a compound, the total oxidation numbers must add up to zero, but in NaF2 they add up to +2 (-1 for each fluorine and +1 for sodium), which is incorrect. The correct formula should be NaF.
The ionic compound formed when sodium (Na) and fluorine (F) react is sodium fluoride, with the chemical formula NaF. In this compound, sodium (Na) donates an electron to fluorine (F) to form an ionic bond between the positively charged Na+ ion and the negatively charged F- ion.
