    Question

    Which of the following is an example of a molecule

    formed through covalent bonding?
    A Sodium chloride Correct Answer Incorrect Answer
    B Magnesium oxide Correct Answer Incorrect Answer
    C Water Correct Answer Incorrect Answer
    D Potassium bromide Correct Answer Incorrect Answer

    Solution

    Water (H₂ O) is a molecule formed through covalent bonds where the oxygen atom shares electrons with two hydrogen atoms. This type of bonding involves the mutual sharing of electrons between atoms, typically occurring between nonmetal atoms. It contrasts with ionic bonds, as seen in sodium chloride and magnesium oxide, where electrons are transferred from one atom to another, creating charged ions.
