    • What is the electron configuration?
      How the electrons are arranged around the nucleus in shells
    • For the first twenty elements, how many electrons can they hold in the first three shells?
      1st shell= 2 maximum electrons
      2nd + 3rd shell= maximum of eight electrons
    • How can the electronic structure of an atom be represented?

      Electronic configuration- by numbers or by a diagram
