The 1 text st IE order of 3 text rd period is Na < Al < Mg < Si < S < P < Cl < Ar X Y are A r C l Z is sodium (Na).

Q. The first ionization energy of magnesium is smaller as compared to that of elements $X$ and $Y$ , but higher than that of $Z$ . the elements $X, Y$ and $Z$ , respectively, are:

chlorine, lithium and sodium

argon, lithium and sodium

argon, chlorine and sodium

neon, sodium and chlorine

The $1^{st}$ IE order of $3^{rd}$ period is

$N a < A l < M g < S i < S < P < Cl < A r$

$X & Y$ are $A r & Cl$

$Z$ is sodium $(N a)$ .
