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.
