惰性气体, 稀有气体
any of the elements in Group 18 of the periodic table, including helium, neon, argon, krypton, xenon, and radon, characterized by their inert nature and stable electron configurations
- Helium, a noble gas, is known for its low density and is often used in balloons to make them float.
氦气是一种惰性气体，以其低密度而闻名，常用于气球中使其漂浮。
- Neon signs emit light when an electrical current passes through neon gas, showcasing the unique properties of noble gases.
霓虹灯标志在电流通过氖气时发光，展示了惰性气体的独特性质。
- Argon, a noble gas commonly used in welding, provides an inert atmosphere to prevent the oxidation of metals during the process.
氩气是一种常用于焊接的惰性气体，它提供了惰性气氛以防止金属在过程中氧化。
- Noble gases have complete electron shells, making them chemically inert and less likely to form compounds with other elements.
惰性气体具有完整的电子壳层，这使得它们在化学上惰性，不太可能与其他元素形成化合物。
- The noble gas configuration is characterized by a full outer electron shell, contributing to the stability and lack of reactivity.
