Noble gases such as helium and neon are known for being chemically what?

Explanation

Noble gases, including helium, neon, argon, krypton, xenon, and radon, are chemically inert, meaning they rarely react with other elements because their outer electron shells are already full. This stability is why helium is used to safely fill balloons and neon is used in glowing signs without concern for reactive hazards. Their lack of reactivity distinguishes them from most other elements on the periodic table. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
