Basic Information
* Atomic Number: 16 (This means sulfur has 16 protons in its nucleus)
* Atomic Symbol: S
* Atomic Mass: 32.065 u (This is the average mass of all naturally occurring isotopes of sulfur)
Subatomic Structure
* Protons: 16 (Positively charged particles found in the nucleus)
* Neutrons: 16 (Neutral particles found in the nucleus; the number of neutrons can vary slightly in isotopes)
* Electrons: 16 (Negatively charged particles that orbit the nucleus in electron shells)
Electron Configuration
* 1s² 2s² 2p⁶ 3s² 3p⁴
* This configuration describes how the 16 electrons are distributed across the energy levels (shells) and sublevels (orbitals) around the sulfur atom.
* Shell 1: Contains 2 electrons in the 1s orbital
* Shell 2: Contains 8 electrons (2 in the 2s orbital and 6 in the 2p orbitals)
* Shell 3: Contains 6 electrons (2 in the 3s orbital and 4 in the 3p orbitals)
Valence Electrons
* Sulfur has 6 valence electrons (the electrons in the outermost shell, the 3p orbitals). These electrons are involved in chemical bonding.
Visual Representation
You can visualize the atomic structure of sulfur as a central nucleus (containing 16 protons and 16 neutrons) surrounded by three electron shells. The outermost shell (shell 3) holds the 6 valence electrons that can participate in chemical reactions.
Important Note: This description refers to the most common isotope of sulfur, sulfur-32. There are other isotopes of sulfur with different numbers of neutrons.
