    Question

    Which of the following elements can readily forms the ionic compounds:               

    1. Cu and Cl
    2. Na and Cl
    3. Zn and Ag
    4. Al and Fe

    Hint:

    Ionic compounds are formed between a metal and anon metal.

    The correct answer is: Na and Cl

      • Elements that forms ions are the ones which can easily lose or gain electron.
      • Ionic compounds are formed between a metal and anon metal.
      • Sodium is a metal it easily loses an electron to become cation and chlorine is a halogen easily gains an electron attains noble gas configuration.
      • The elements that can readily forms the ionic compounds are Na and Cl.
