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?
According to Hund's Rule, how do electrons fill orbitals within a subshell?
- They fill the orbitals based on increasing distance from the nucleus.
- They pair up immediately after the first electron enters.
- They occupy orbitals singly before pairing in the same energy level. (correct)
- They fill all orbitals in pairs before moving to the next subshell.

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.
