Question

Atoms of iron (fe) and sulfur (s) form iron sulfide (fes) when the iron atom donates electrons to the sulfur atom. the type of bond formed would be a(n) __________.

Answer 1

The type of bond formed in FeS would be Polar Covalent Bond.

Step-by-step explanation:

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

Less than 0.4 then it is Non Polar Covalent Bond

Between 0.4 and 1.7 then it is Polar Covalent Bond

Greater than 1.7 then it is Ionic Bond

For Fe and S,

E.N of Sulfur = 2.58

E.N of Iron = 1.83

________

E.N Difference 0.75 (Polar Covalent Bond)
