Electronegativity

Electronegativity is the ability of an atom to attract electrons toward itself when it forms a chemical bond with another atom. Atoms with high electronegativity pull electrons more strongly, while atoms with low electronegativity attract electrons weakly.

Fluorine (F) is the most electronegative element.

Metals usually have low electronegativity, while non-metals have high electronegativity.

Trend in the Periodic Table

Electronegativity increases from left to right across a period.

It decreases from top to bottom down a group.

Importance of Electronegativity

It helps to predict the type of bond (ionic or covalent).

A large difference in electronegativity forms an ionic bond.

A small difference forms a covalent bond.

Example

In NaCl, chlorine is more electronegative than sodium, so electrons move toward chlorine.

Conclusion Electronegativity plays an important role in understanding chemical bonding and reactions.
