Text Solution

AI Generated Solution

### Step-by-Step Solution 1. **Identify Noble Gases**: - The noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They belong to Group 18 of the periodic table. 2. **Understand Electronic Configuration**: - The electronic configuration of noble gases is characterized by a completely filled outer shell. For noble gases, this configuration is generally represented as ns²np⁶, where 'n' is the principal quantum number corresponding to the outermost shell. ...

State why noble gases are unreactive while atoms of elements other than noble gases are chemically reactive.

All the noble gases are colourless and tasteless monoatomic gases. In general, noble gases are least reactive and their inertness to chemical reactivity is attributed to the following reasons. Reactive and their inertness to chemical reactivity is attributed to the following reasons. (i)Except helium, all have completely filled ns^(2)np^(6) electronic configuration in their valence shells. (ii)All have high ionisation enthalpy and more positive electron gain enthalpy. However, a number of xenon compounds mainly with most electronegative elements like fluorine and oxygen have been synthesized under different conditions and fluorides of xenon have been used as an oxidising agent and a fluorinating agent in many of the chemical reactions Select the correct statement.
