Sulfur's Electronic Configuration:
* Atomic Number: 16 (meaning it has 16 protons and 16 electrons)
* Electronic Configuration: 1s² 2s² 2p⁶ 3s² 3p⁴
Orbital Notation:
* 1s: ↑↓ (2 electrons)
* 2s: ↑↓ (2 electrons)
* 2p: ↑↓ ↑↓ ↑ (6 electrons)
* 3s: ↑↓ (2 electrons)
* 3p: ↑↓ ↑ (4 electrons)
Explanation:
* Orbitals: Electrons occupy specific regions of space around the nucleus called orbitals. We use the principle quantum number (n) to indicate the energy level (1, 2, 3, etc.) and letters (s, p, d, f) to represent the orbital shapes.
* s Orbitals: Each s orbital can hold a maximum of 2 electrons.
* p Orbitals: Each p subshell has three orbitals (px, py, pz), each capable of holding 2 electrons.
* Hund's Rule: Electrons individually fill each orbital within a subshell before pairing up.
* Pauli Exclusion Principle: Each orbital can hold a maximum of 2 electrons, and they must have opposite spins (represented by arrows pointing up and down).
Key Points:
* Sulfur has 6 valence electrons (electrons in the outermost shell).
* These valence electrons determine sulfur's chemical behavior.
* The orbital notation helps visualize how the electrons are distributed in the atom.
