Question 9

Chemical Bonding

The diagram above represents an atom that can combine with chlorine to form

Diagram for this question
  1. A.a covalent bond
  2. B.an electrovalent bond
  3. C.a hydrogen bond
  4. D.a co-ordinate bond.
Show the answer and explanation

Answer: B (an electrovalent bond)

Explanation

The atom shown has only two electrons in its outermost shell, so it is a metal that easily loses them. A metal losing electrons to chlorine forms ions, which is an electrovalent (ionic) bond.
