6. In the three molecules, O2, HCl, and F2, what atom would have a partial negative charge?1 pointoxygenfluorinechlorinehydrogen

To determine which atom in the molecules O₂, HCl, and F₂ would have a partial negative charge, we should consider the electronegativity of the atoms involved in each molecule.

1. Electronegativity Concept: Electronegativity is a measure of an atom's ability to attract and hold onto electrons. In a bond between two different atoms, the more electronegative atom will have a partial negative charge.

2. Molecule Analysis:

   • O₂: This molecule is diatomic and consists of two oxygen atoms bonded together. Because they have the same electronegativity, there is no partial negative or positive charge.
   • HCl: This molecule consists of hydrogen and chlorine. Chlorine is more electronegative than hydrogen, so chlorine will have a partial negative charge (δ-) while hydrogen will have a partial positive charge (δ+).
   • F₂: Similar to O₂, this diatomic molecule consists of fluorine atoms. With identical electronegativity, there are no charges on either atom.

3. Conclusion: In HCl, the chlorine atom carries a partial negative charge.

Final Answer

The atom that would have a partial negative charge is chlorine (in HCl).
