Take This Difficult Chemistry Quiz

In metals, the atoms are placed together really closely, and this causes some of the outer electrons to break free and float around within the structure of the metal. We say that the electrons are delocalized. Because they have lost electrons, metal atoms are metal ions, but you don't notice this because of the delocalized electrons. Here's the Chemistry you've been waiting for, let's see how well you do on it.
