Question

The molecule hydrogen fluoride (HF) contains a polar bond H - F, where fluorine is more electronegitivexpensive than Hydrogen. Which is the appropriate representation of the H - F bond?

Answer 1

Hydrogen's one electron will see that fluoride has seven electrons on its valence shell and will want to fill that eight slot to create the more stable compound Hydrogen fluoride. The flouride atom will have eight electrons orbiting its valence shell while hydrogen will have two electrons.
