What is an Atom?

An atom is the smallest constituent unit of matter that retains the properties of an element. It consists of a dense nucleus containing protons and neutrons, surrounded by electrons in orbital shells. The arrangement and number of these particles determine the element's identity and chemical properties.

Key Components:

  • • Nucleus: Dense core containing protons and neutrons
  • • Electron Cloud: Probability regions where electrons are found
  • • Atomic Number (Z): Number of protons (element identity)
  • • Mass Number (A): Total nucleons (protons + neutrons)
