Questions and Answers

Which principle states that electrons will fill the lowest energy orbitals first?

  • Minimum Energy Principle (correct)
  • Quantum Spin Rule
  • Hund's Rule
  • Pauli Exclusion Principle
  • What does the Pauli Exclusion Principle state about electrons in an atom?

  • No two electrons can have the same set of four quantum numbers. (correct)
  • Electrons fill orbitals based on increasing energy.
  • Electrons must be paired in all orbitals.
  • Electrons can share orbitals with identical quantum numbers.
  • According to Hund's Rule, how do electrons fill orbitals within a subshell?

  • They fill the orbitals based on increasing distance from the nucleus.

    Study Notes

    Atomic Electronic Configuration

    • Electrons occupy orbitals in a specific order based on the Minimum Energy Principle: electrons first enter the orbital with the lowest energy level.
    • The Pauli Exclusion Principle dictates that no two electrons within an atom can share the same set of four quantum numbers.
    • Hund's Rule states that electrons individually occupy orbitals within a subshell before pairing up.
    • Diagrams illustrating electron configuration depict electrons as arrows, representing their spin and illustrating the filling of orbitals and subshells.
    • The document likely draws a connection between electronic configuration and the workings of an LED (Light Emitting Diode), possibly in the context of circuits or electrical connections.
    • Portions of the text mention a trip or activity, suggesting this document may be part of a learner's notebook or a supplementary resource.
    • Some Polish text presence indicates the document might be from a Polish-speaking educational context.
    • As image quality is limited, some portions of the document are not fully legible, impacting complete understanding of its context.
