Most of the noble gas compounds are formed by xenon-why? |
| Answer» Solution :XENON has the second LARGEST atomic SIZE in group- 18 (next to radon). This leads to a MUCH lower ionisation enthalpy of Xe as compared to other members of the group. So, highly electronegative elements like `O_(2)` and `F_(2)` form COVALENT bonds with Xe by transferring its p -electrons to its vacant d -orbital. Hence, most of the noble gas compounds are formed by Xe. | |
