Question 8

Chemical Bonding

If the difference in electronegativity of elements P and Q is 3.0, the bond that will be formed between them is

  1. A.metallic.
  2. B.covalent.
  3. C.co-ordinate.
  4. D.ionic.
Show the answer and explanation

Answer: D (ionic.)

Explanation

A large electronegativity difference (above about 1.7) means one atom takes electrons from the other, so the bond is ionic.
