1. Electronic Configuration:
* 1s² 2s² 2p⁶ 3s² 3p⁴
2. Orbital Diagram:
* 1s: ↑↓
* 2s: ↑↓
* 2p: ↑↓ ↑↓ ↑↓
* 3s: ↑↓
* 3p: ↑↓ ↑ ↑
Explanation:
* Orbitals and Hund's Rule: The orbital diagram shows the arrangement of electrons within each subshell. Hund's Rule states that electrons will individually occupy each orbital within a subshell before doubling up in any one orbital.
* Pauli Exclusion Principle: Each orbital can hold a maximum of two electrons, and they must have opposite spins (one spin up, one spin down).
Important Notes:
* Subshells: The 's' subshells have one orbital, the 'p' subshells have three orbitals, and so on.
* Spin: The arrows represent the spin of the electrons. "↑" represents spin up, and "↓" represents spin down.
