Inert elements, also known as noble gases, are a group of elements that have very low reactivity due to their stable electron configurations. The noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
Here are the symbols and atomic masses of these inert elements:
- Helium (He) - Atomic mass: 4.0026 amu
- Neon (Ne) - Atomic mass: 20.1797 amu
- Argon (Ar) - Atomic mass: 39.948 amu
- Krypton (Kr) - Atomic mass: 83.798 amu
- Xenon (Xe) - Atomic mass: 131.293 amu
- Radon (Rn) - Atomic mass: 222.0176 amu
These atomic masses are approximate values and may have slight variations as more accurate measurements are made.
