Final answer:
The structural formula for HF is H-F, where the fluorine atom receives the delta minus (δ-) charge and the hydrogen atom receives the delta plus (δ+) charge.
Step-by-step explanation:
The structural formula for HF is H-F, with the hydrogen atom bonded to the fluorine atom. In this molecule, the fluorine atom receives the delta minus (δ-) charge, while the hydrogen atom receives the delta plus (δ+) charge. This is because the electrons in the bond are closer to the fluorine atom, making it partially negative, while the hydrogen atom becomes partially positive.
In the structural formula, the fluorine atom (F) will have a partial negative charge represented by δ-, and the hydrogen atom (H) will have a partial positive charge represented by δ+.
