Chemistry: Electron affinity: period trend
Beschrijving
Electron affinity is the change in energy when a neutral atom in its gaseous form gains an electron to form a negative ion. For example, when a neutral fluorine atom in its gas state gains an electron, it releases energy to form a fluoride ion.
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!
