Neon, a noble gas, is well known for producing what distinctive effect when electrified inside illuminated signs?

Explanation

Neon, a noble gas present in only trace amounts in Earth’s atmosphere, is well known for producing a distinctive, vivid orange-red glow when an electric current passes through a sealed glass tube containing the gas, a phenomenon widely used in illuminated neon signs. Different gases and gas mixtures used in similar sign-making techniques can produce a range of other colors as well, though the term neon sign is often used broadly regardless of the exact gas used. As a noble gas, neon is chemically inert, meaning it does not readily react with other substances under normal conditions. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
