D
Ionic bond
Verified step by step guidance1
Identify the types of chemical bonds listed: metallic, covalent, hydrogen, and ionic.
Understand that a covalent bond involves the sharing of electron pairs between atoms.
Recognize that in a water molecule (H₂O), the oxygen atom shares electrons with two hydrogen atoms through covalent bonds.
Explain that the oxygen atom is more electronegative than the hydrogen atoms, meaning it attracts the shared electrons more strongly.
Conclude that this unequal sharing of electrons in the covalent bonds creates a partial negative charge on the oxygen and a partial positive charge on the hydrogens, resulting in polarity within the water molecule.
