Atomic Structure and Subatomic Particles

The nucleus is at the very center of an atom. It's incredibly dense and contains two of these particles:
* Protons: These have a positive electrical charge (+1). The number of protons in an atom determines what element it is. For example, all carbon atoms have 6 protons. This number is called the atomic number.
* Neutrons: These have no electrical charge (they're neutral). They help stabilize the nucleus. The number of neutrons can vary within atoms of the same element, leading to different isotopes.
