Final answer:
option c,The ionic compound formed between sodium (Na+) and fluoride (F-) is NaF, known as sodium fluoride.
Step-by-step explanation:
When sodium (Na+) and fluoride (F-) ions come together to form an ionic compound, they do so in a one-to-one ratio to balance the positive and negative charges. Therefore, the correct formula for the ionic compound formed between Na and F is NaF, known as sodium fluoride. Each sodium cation, with a single positive charge, will combine with one fluoride anion, which has a single negative charge, resulting in a neutrally charged compound.
The ionic compound that would form when Na and F ions come together is NaF.
When sodium (Na) loses an electron, it forms a sodium cation (Na+), which has a positive charge. When fluorine (F) gains an electron, it forms a fluoride anion (F-), which has a negative charge. These ions are then attracted to each other due to their opposite charges, resulting in the formation of an ionic compound called sodium fluoride (NaF).
The chemical formula NaF represents the ratio of sodium cations to fluoride anions in the compound, with a 1:1 ratio.
