Arrange thefollowingions in order ofdecreasingionicradii: Li^(2+), He ^(+) , Be^(3+) |
| Answer» Solution :`He^(+) , LI^(2+)` and `Be^(3+)` are allisoelectronicions. Amongisoelectronicionsionicradiusdecreasesas the positivechargeincreases.Therefore theionicradiidecreasesin the order `: He^(+) GT Li^(2+) gt Be^(3+)` | |
