Question

in a biology lab, a researcher is studying a water molecule. she notices that the oxygen atom has a partial negative charge and the hydrogen atoms have partial positive charges. what type of bond is responsible for the attraction between the oxygen and hydrogen atoms within the water molecule?
○ polar covalent bond
○ ionic bonds
○ hydrogen bonds
○ nonpolar covalent bond

Explanation:

Water (H₂O) has a polar covalent bond between oxygen and hydrogen atoms. Oxygen is more electronegative, causing unequal sharing of electrons and partial charges. This polarity leads to the attraction between oxygen and hydrogen atoms within water molecules. Ionic bonds involve transfer of electrons between ions, non - polar covalent bonds have equal electron sharing, and hydrogen bonds are intermolecular forces between water molecules, not the bond within a water molecule.

Answer:

polar covalent bond
