Electronegativity
A measure of how strongly an atom attracts the shared electrons in a covalent bond toward itself. Explains why water is polar, why some molecules have dipole moments.
💡 Intuition
How 'greedy' an atom is for electrons. Fluorine is most greedy.
Core Idea
Electronegativity differences between bonded atoms determine whether a bond is polar or nonpolar.
🔬 Example
🎯 Why It Matters
Explains why water is polar, why some molecules have dipole moments.
⚠️ Common Confusion
Large difference → ionic bond. Small difference → nonpolar covalent. Medium → polar covalent.
How to Use Electronegativity
When this concept appears in chemistry, it usually controls how you interpret a representation, a quantity, or a change in a system. Students make faster progress when they can explain what electronegativity tells them before reaching for an equation or memorized phrase.
A strong self-check is to say what electronegativity does, what it does not do, and which nearby idea it is easiest to confuse with. That kind of explanation makes later calculations, lab reasoning, and compare pages much more reliable.

How Electronegativity Connects to Other Ideas
To understand electronegativity, you should first be comfortable with covalent bond. Once you have a solid grasp of electronegativity, you can move on to polar covalent and polarity.
