    V3 - B) A nonmetal that gained three electrons

    X - A) A nonmetal that gained one electron

    Y + C) A metal that lost one electron

    Z3 + D) A metal that lost three electrons

    Explanation Neutral atoms of elements in the periodic table react by gaining or losing electrons to attain a stable configuration according to the octet rule. Atoms of metals react by losing electrons to attain a stable configuration and form positively charged ions known as cations. For example, a neutral sodium atom, Na, would gain one electron to form a cation of sodium, Na⁺. Atoms of non-metals, on the other hand, react by gaining electrons to attain stable configuration and form negatively charged ions known as anions. For instance, a neutral chloride, Cl, atom requires to gain one electron to attain stability and form a chloride anion, Cl⁻.
