Electronegativity

Electronegativity is a model for an atom’s tendency to attract electron density when it is bonded.

Why scientists care

Electronegativity is a model for an atom’s tendency to attract electron density when it is bonded.

Differences in electronegativity help us reason about bond polarity, but they do not turn bonding into a rigid binary classification.

A concrete example

A polar H–F bond reflects fluorine's much stronger attraction for bonding electrons.

Try to notice

Science becomes memorable when a definition is connected to something measurable or observable.

The key idea

Electronegativity is a model for an atom’s tendency to attract electron density when it is bonded.

Why it matters

Differences in electronegativity help us reason about bond polarity, but they do not turn bonding into a rigid binary classification.
