How does electronegativity affect the type of chemical bond?

Differences in electronegativity (ΔEN) affect the type of chemical bond.

Atoms with precise or nearly exact electronegativity (Δ EN <0.5) form non-polar covalent bonds.

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

Atoms with slightly different electronegativities (0.5 <Δ EN 1.7) form polar covalent bonds.



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
