* Sulfur ions can be either negatively or positively charged. Sulfur can gain or lose electrons to form ions.
* A sulfur ion with a negative charge (an anion) has more electrons than a neutral sulfur atom. A neutral sulfur atom has 16 electrons. For example, a sulfide ion (S⁻²) has gained two electrons, bringing the total to 18.
* A sulfur ion with a positive charge (a cation) has fewer electrons than a neutral sulfur atom. For example, a sulfur cation (S²⁺) has lost two electrons, bringing the total to 14.
Understanding Sulfur's Electron Configuration:
* Sulfur's atomic number is 16, meaning it has 16 protons and 16 electrons in its neutral state.
* Its electron configuration is 2, 8, 6. This means it has 6 electrons in its outermost shell (valence electrons), which are involved in chemical bonding.
Key Point: The number of electrons in a sulfur ion will always be different from a neutral sulfur atom, depending on whether it has gained or lost electrons.
