Vedclass · Answer

(B) The ionization potential $(IP)$ generally increases across a period from left to right and decreases down a group.Comparing the elements $B$ (Boron,group $13$,period $2$),$Li$ (Lithium,group $1$,period $2$),and $K$ (Potassium,group $1$,period $4$):$1$. $B$ is in period $2$ and group $13$,so it has a higher $IP$ than $Li$ (group $1$,period $2$).$2$. $Li$ is in period $2$ and $K$ is in period $4$ (same group $1$),so $Li$ has a higher $IP$ than $K$.Therefore,the correct order is $B > Li > K$.

Which of the following sets is correct regarding the ionization potential?
