Chemistry: Mini-video on ion size

Correcting a mistake and learning a bit about ion size

Chemistry Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful. Periodic table trends Have you ever wondered why it is called the "periodic" table? The elements are organized based on their electronic structure, which results in some interesting trends in atomic properties as you move down a group or across a period. This tutorial will try to explain some of those trends! Topic: Science Learn about all the sciences, from physics, chemistry and biology, to cosmology and astronomy, across hundreds of videos, articles and practice questions.
