Transcribed Image Text:The image displays four options representing electronic configurations using the Aufbau principle, showcasing the distribution of electrons in atomic orbitals. Each option consists of labeled sections for 1s, 2s, and 2p orbitals, with electrons represented by arrows.
### Options:
1. **First Option:**
- **1s Orbital:** Two arrows pointing in opposite directions (up and down), indicating an electron pair.
- **2s Orbital:** Two arrows pointing in opposite directions (up and down), indicating an electron pair.
- **2p Orbitals:** Two arrows pointing in opposite directions (up and down) in the first circle, and two empty circles.
2. **Second Option:**
- **1s Orbital:** Two arrows pointing in opposite directions (up and down).
- **2s Orbital:** Two arrows pointing in opposite directions (up and down).
- **2p Orbitals:** Three arrows pointing upwards, each in separate circles.
3. **Third Option:**
- **1s Orbital:** Two arrows pointing in opposite directions (up and down).
- **2s Orbital:** Two arrows pointing in opposite directions (up and down).
- **2p Orbitals:** Four arrows, with three pointing upwards in separate circles and one paired with a downward arrow in a circle.
4. **Fourth Option:**
- **1s Orbital:** Two arrows pointing in opposite directions (up and down).
- **2s Orbital:** Two arrows pointing in opposite directions (up and down).
- **2p Orbitals:** Each circle has one arrow pointing up.
These diagrams illustrate how electrons fill the 1s, 2s, and 2p orbitals according to the rules of electron configuration, such as the Pauli exclusion principle and Hund's rule.

Transcribed Image Text:**Task: Orbital Diagrams and the Pauli Exclusion Principle**
**Instruction:**
Select each of the orbital diagrams that are allowed according to the Pauli Exclusion Principle.
**Listen Button:**
(There is a button available to listen to the text.)
**Explanation:**
The Pauli Exclusion Principle states that no two electrons in the same atom can have identical quantum numbers. This means in any given orbital, the two electrons must have opposite spins. When reviewing orbital diagrams, ensure that no more than two electrons occupy any single orbital and that they have opposite spins.
For further explanation or examples of allowed diagrams, refer to additional resources or interactive diagrams provided on the website.
