Study Notes
Noble Gases
- Group VIA elements (e.g., oxygen, sulfur) try to gain two electrons during chemical changes to achieve a full outer energy level, which is a stable configuration similar to that of noble gases.
Noble Gases Characteristics
- Group VIIIA elements (noble gases) like neon are unreactive because they have a full outer energy level, which makes them stable and prevents them from reacting with other elements.
Non-Reactivity of Helium and Neon
- Helium and neon do not participate in chemical changes because they have a full outer energy level, which makes them extremely stable and unreactive.
Stability of Octet Configuration
- A species (atom or ion) with eight electrons in the valence shell is stable due to its full outer energy level, which is a configuration similar to that of noble gases.
