Answer :
Final answer:
In nitrogen trifluoride, the partial negative charge is concentrated on the fluorine atoms due to their higher electronegativity compared to nitrogen. This makes fluorine the region of negative charge in the molecule. Therefore, fluorine is the answer to the student's question.
Explanation:
Understanding Partial Charges in Nitrogen Trifluoride
Nitrogen trifluoride (NF3) is a covalent compound where nitrogen is bonded to three fluorine atoms. In this molecule, the electronegativity of the atoms plays a crucial role in determining the location of the partial charges.
Fluorine is significantly more electronegative than nitrogen, which means it attracts the bonding electrons more strongly. As a result, the bonding pairs of electrons spend more time closer to the fluorine atoms rather than the nitrogen atom. This leads to a partial negative charge ( extbf{ extit{δ-}}) accumulating around the fluorine atoms, and consequently, a partial positive charge ( extbf{ extit{δ+}}) at the nitrogen atom.
Therefore, to answer the student's question, the partial negative charge in nitrogen trifluoride will be located around the fluorine atoms.
