Final answer:
A Noble Gas is an inert/unreactive element with a full outer shell. It is also a type of gas. Noble Gases include elements such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
Step-by-step explanation:
A Noble Gas is an inert/unreactive element with a full outer shell. It is also a type of gas. Noble Gases include elements such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are known for their stability and lack of reactivity, making them useful in various applications such as lighting, lasers, and cryogenics.
