Electron configuration

• What is electron configuration?

  Electron arrangement in an atom
• What does electron configuration show?

  The arrangement of electrons in shells
• What are the energy levels in electron configuration?

  Shells where electrons are arranged
• How do we determine the electron configuration?

  By using the maximum distribution of electrons
• What is the maximum number of electrons in the first four energy levels?

  2, 8, 8, 2
• What does the notation "4s" represent in electron configuration?

  The energy level and subshell of an electron
• What element has the electron configuration of Sc 21?

  Scandium
• What is the structure of electron configuration?

  • Arrangement of electrons in shells
  • Energy levels indicate electron distribution
  • Maximum distribution: 2, 8, 8, 2
• What does the inner shell nearest the nucleus refer to?

  The first energy level of an atom
• How is the electron configuration visually represented?

  Through diagrams showing electron shells
• What does the notation "1 shell" indicate?

  The first energy level of an atom
• Shells are further divided into subshells, which have different shapes and orientations.
• Electrons are arranged into shells, with each shell having a maximum number of electrons it can hold (2, 8, or 18).
• The magnetic quantum number (m) indicates the orientation of an orbital around the nucleus.
• The electron configuration is the arrangement of electrons within an atom.
• The azimuthal quantum number (l) specifies the shape of the orbital where an electron is likely to be found.
• The principal quantum number (n) determines the main energy level of an electron in an atom.
• Each element has its own unique electron configuration that determines its chemical properties.
• Each orbital has a specific capacity for holding electrons based on its shape and orientation.
