Final answer:
The formula for ammonium fluoride is NH4F, where the +1 charged ammonium ion (NH4+) combines with the -1 charged fluoride ion (F-) in a 1:1 ratio. The correct answer is E. NH₄F.
Step-by-step explanation:
The formula NH₄F represents ammonium fluoride. In this compound, the ammonium ion (NH₄⁺) consists of one nitrogen atom bonded to four hydrogen atoms, providing a net positive charge of +1. The fluoride ion (F⁻) is a single negatively charged fluorine atom. The combination of these ions forms a stable ionic compound with an overall neutral charge.
The balanced chemical equation for the formation of ammonium fluoride is as follows:

This equation illustrates the 1:1 ratio between the ammonium ion and the fluoride ion, resulting in the formation of ammonium fluoride. It's essential to recognize the charges of each ion and ensure that they combine in a way that maintains overall electrical neutrality in the compound.
The correct answer is E. NH₄F.
