Why Are Group 18 Elements Called Noble Gases?
Discover why Group 18, not Group 7, is called the noble gases due to their stability and inertness on the periodic table.
18 views
Group 7 is not called the noble gases; it's actually Group 18 that's referred to as the noble gases. This name is given because they are very stable and unreactive due to their complete valence electron shells. This chemical inertness makes them unique in the periodic table, symbolizing 'nobility' in their reluctance to react with other elements.
FAQs & Answers
- What elements are in Group 18 of the periodic table? Group 18 elements include helium, neon, argon, krypton, xenon, and radon, all known as noble gases due to their stable electron configurations.
- Why are noble gases considered inert or unreactive? Noble gases have full valence electron shells, making them chemically stable and unlikely to react with other elements.
- Is Group 7 called noble gases? No, Group 7 elements are not called noble gases; they are halogens and are more reactive compared to the noble gases in Group 18.
