Question

How does electronegativity affect the type of bond?

Answer 1

The differences in electronegativity (`Δ"EN"`) affect the type of bond.

Explanation:

Atoms with the exact or nearly exact electronegativities (`Δ"EN < 0.5"`) form non polar covalent bonds.

Atoms with extremely different electronegativities (`Δ"EN > 1.7"`) form ionic bonds.

Atoms with somewhat different electronegativites (`0.5 < Δ"EN < 1.7"`) form polar covalent bonds.
