Vedclass · Answer

(D) The ionic radius increases down a group and decreases across a period from left to right.For the given elements,$Mg$ ($2^{nd}$ group,$3^{rd}$ period) has the smallest size.$Na$ ($1^{st}$ group,$3^{rd}$ period) is larger than $Mg$.$K$ ($1^{st}$ group,$4^{th}$ period) is larger than $Na$.$Rb$ ($1^{st}$ group,$5^{th}$ period) is the largest.Therefore,the increasing order of ionic radii is $Mg < Na < K < Rb$.

Which of the following is the correct increasing order of ionic radii for $Na, Rb, K,$ and $Mg$?
