What's the difference between electron affinity and electronegativity?
They follow similar periodic trends, but they mean completely different things — and mixing them up is one of the most common mistakes in chemistry.
In this video, we’ll walk through:
🔹What electron affinity and electronegativity actually mean
🔹How they're used in general chemistry
🔹Why one is measured and the other does not have units
🔹Real-world examples: H₂O (electronegativity) and Cl⁻ ion formation (electron affinity)
This video is relevant for AP Chemistry, IB, or General Chemistry 1 — or if you just want to truly understand how electronegativity and electron affinity are different.
