   What is atomic structure?

   • The atomic structure refers to the composition and organization of atoms, the basic units of matter. At the center of an atom is the nucleus, which contains protons (positively charged particles) and neutrons (neutral particles) The atomic model which we study today was not given at one time.

   What is a second atom?

   • Electron states in an atom are associated with different energy levels, and in transitions between such states they interact with a very specific frequency of electromagnetic radiation. This phenomenon serves as the basis for the International System of Units ' (SI) definition of a second : The second, symbol s, is the SI unit of time.
