  • What principle states that an orbital can hold a maximum of two electrons with opposite spins?
    The Pauli exclusion principle states that an orbital can hold a maximum of two electrons with opposite spins.
  • What is the key difference between paramagnetic and diamagnetic substances?
    Paramagnetic substances have at least one unpaired electron, while diamagnetic substances have all electrons paired.
  • How do paramagnetic substances respond to magnetic fields?
    Paramagnetic substances are influenced by magnetic fields because they have unpaired electrons.
  • What is the electron configuration requirement for a diamagnetic substance?
    A diamagnetic substance must have all electrons paired in every orbital.
  • What happens if there is at least one unpaired electron in an orbital?
    The substance is classified as paramagnetic and will be affected by magnetic fields.
  • How are electrons arranged in a diamagnetic substance's orbitals?
    All electrons are paired in every orbital in a diamagnetic substance.
  • What does the presence of unpaired electrons indicate about a substance's magnetic properties?
    It indicates that the substance is paramagnetic and magnetic.
  • What is the magnetic property of a substance with all paired electrons?
    The substance is diamagnetic and is not affected by magnetic fields.
  • Why is it important to know if an element or ion is paramagnetic or diamagnetic?
    It helps determine their electron configurations and magnetic properties.
  • What is the maximum number of electrons that can occupy a single orbital?
    A single orbital can hold a maximum of two electrons.
  • What must be true about the spins of two electrons in the same orbital?
    The two electrons must have opposite spins.
  • How can you identify a paramagnetic element or ion from its electron configuration?
    If there is at least one unpaired electron in any orbital, it is paramagnetic.
  • What is the effect of a magnetic field on diamagnetic substances?
    Diamagnetic substances are unaffected by magnetic fields.
  • What is the effect of a magnetic field on paramagnetic substances?
    Paramagnetic substances are attracted to magnetic fields.
  • What should you look for in electron configurations to determine if a substance is diamagnetic?
    Check that every orbital contains two electrons, meaning all are paired.
