    In the transition of \[Zn\] atoms to \[Z{{n}^{++}}\]ions there is a decrease in the                                              [CPMT 1972]

    A)                 Number of valency electrons

    B)                 Atomic weight

    C)                 Atomic number

    D)                 Equivalent weight

    Correct Answer: A

    Solution :

                    Ion is formed by gaining or losing electrons. To form cation electron are lost from the valency shell, so Zn atoms to \[Z{{n}^{++}}\] ions there is a decrease in the no. of valency electron.
