What is Understanding Atoms and Isotopes about?
Atoms are the smallest particles of matter and consist of a nucleus surrounded by electrons. The nucleus contains protons and neutrons, while electrons orbit around the nucleus. Elements are identified by their atomic number, which is the number of protons, and isotopes are atoms of the same element with different numbers of neutrons. Electrons fill energy levels in a predictable pattern for the first 20 elements.
