    the periodic table?
    A Group 2 and group 17 Correct Answer Incorrect Answer
    B Group 1 and group 3 Correct Answer Incorrect Answer
    C Group 1 and group 17 Correct Answer Incorrect Answer
    D Group 2 and group 4 Correct Answer Incorrect Answer

    Solution

    Hydrogen is unique in that it shares properties with both Group 1 (alkali metals) and Group 17 (halogens). Like alkali metals, it has one electron in its outer shell and can lose it to form a cation. Similarly, it can gain an electron like halogens to form an anion, displaying a dual nature.
