What is atomic structures?


Wiki User

All atoms consist of two regions. The nucleus is a very small region located near the center of an atom. In every atom the nucleus contains at least one positively charged particle called a proton and usually one or more neutral particles called neutrons. Surrounding the nucleus is a region occupied by negatively charged particles called electrons. This region is very large compared with the size of the nucleus. Protons, neutrons, and electrons are often referred to as subatomic particles.
