  • What is the maximum number of electrons that can occupy a single orbital?
    A single orbital can hold a maximum of two electrons.
  • According to the Pauli exclusion principle, what must be true about the spins of two electrons in the same orbital?
    The two electrons must have opposite spins; one spin-up and one spin-down.
  • What are the possible values for electron spin in an orbital?
    The possible values are +1/2 (spin-up) and -1/2 (spin-down).
  • How is a spin-up electron represented in orbital diagrams?
    A spin-up electron is represented by an arrow pointing up.
  • How is a spin-down electron represented in orbital diagrams?
    A spin-down electron is represented by an arrow pointing down.
  • What does the electron spin value of +1/2 indicate about its rotation?
    +1/2 indicates the electron is spinning clockwise.
  • What does the electron spin value of -1/2 indicate about its rotation?
    -1/2 indicates the electron is spinning counterclockwise.
  • Why can't two electrons in the same orbital have the same spin?
    Because the Pauli exclusion principle forbids identical spins in the same orbital.
  • What principle governs the arrangement of electron spins in an orbital?
    The Pauli exclusion principle governs electron spin arrangement.
  • What is the significance of using arrows in orbital diagrams?
    Arrows visually represent the direction of electron spin within an orbital.
  • If an orbital contains two electrons, how must their spins be oriented?
    Their spins must be opposite: one up (+1/2) and one down (-1/2).
  • What does 'spin-up' mean in terms of electron movement?
    Spin-up means the electron is spinning clockwise.
  • What does 'spin-down' mean in terms of electron movement?
    Spin-down means the electron is spinning counterclockwise.
  • How do you start filling an orbital with electrons according to the lesson?
    You start with an electron pointing up, followed by one pointing down.
  • What is the relationship between electron spin values and their rotational direction?
    A spin value of +1/2 corresponds to clockwise rotation, and -1/2 to counterclockwise rotation.
