Chem Basics
... Model 2: Although an atom is defined by it’s protons, it’s the electrons that determine how it will behave. In a neutral atom (no charge), the number of protons and electrons is equal. The electrons move within ‘shells’ or ‘orbits’ about the nucleus; those in the outermost shell are called valence e ...
