Na arrow[ Ne ] 3 s 1 IE 1 is very low but IE 2 is very high due to stable noble gas configuration of Na + Mg arrow[ Ne ] 3 s 2 IE 1 IE 2 arrow Low IE 3 is very high.

Q. Identify the elements $X$ and $Y$ using the ionisation energy values given below:

$X = N a; Y = M g$

$X = M g; Y = F$

$X = M g; Y = N a$

$X = F; Y = M g$

$N a \to [N e] 3 s^{1} I E_{1}$ is very low but $I E_{2}$ is very high due to stable noble gas configuration of $N a^{+}$

$M g \to [N e] 3 s^{2} I E_{1} & I E_{2} \to$ Low $I E_{3}$ is very high.

Q. Identify the elements X and Y using the ionisation energy values given below:

X=Na;Y=Mg

X=Mg;Y=F

X=Mg;Y=Na

X=F;Y=Mg
