Vedclass · Answer

(D) The ionisation potential generally decreases down a group and increases across a period from left to right. $B$ (Boron) is a non-metal in period $2$,which has a high ionisation potential. $K$ (Potassium) and $Cs$ (Caesium) are alkali metals in group $1$,where $Cs$ is below $K$,so $Cs$ has a lower ionisation potential than $K$. $U$ (Uranium) is an actinoid with a relatively low ionisation potential compared to non-metals like $B$. Comparing these,the correct order of increasing ionisation potential is $Cs < U < K < B$.

With reference to the concept of ionisation potential,which one of the following sets is correct?
