Which of the following pairs of atoms exhibit an ionic bond?

H and S

Fe and O

C and F

C and N

2 Answer

  • Fe & O makes an ionic bond because of this┬á
    Metal and Metal = Metallic
    Non-Metal and Metal = Ionic
    Non-Metal and Non-Metal = Covalent
    In this case Oxygen (O) is a Non-Metal and Iron (Fe) is a Metal so you have an Ionic Bond
  • Fe and O because Fe (Iron) is a metal, and O(oxygen) is a nonmetal. Ionic bond forms between a metal and a nonmetal, not nonmetal and nonmetals like C and N
