Final answer:
Helium (b. Helium) from the provided options is a noble gas. It is part of Group 18 on the periodic table, which consists of unreactive, monatomic gases used in various applications like welding and lighting.
Step-by-step explanation:
The element helium (b. Helium) is a noble gas. Noble gases, which include helium, neon, argon, krypton, xenon, and radon, are categorized in Group 18 of the periodic table. These gases are monatomic and unreactive under standard room temperature and pressure, leading to their historical designation as inert or rare gases.
Helium is used in various applications due to its low reactivity, such as providing an inert atmosphere for welding and filling balloons. Other noble gases like neon are utilized in lighting, for example, in neon lights due to the red light they emit in a gas discharge tube.
