Noble gases are a group of chemical elements found in Group 18 of the periodic table. They include helium, neon, argon, krypton, xenon, and radon. These gases are characterized by their lack of color, odor, and taste, and they are known for being chemically inert, meaning they do not easily react with other elements. Due to their stability, noble gases have various applications. For example, helium is used in balloons and as a cooling medium in cryogenics, while neon is commonly found in colorful signs. Their unique properties make them valuable in scientific research and industrial processes.
