Question

The correct sequence of elements in decreasing order of first ionisation energy is

(a) $N a > M g > A l$
$M g > N a > A l$
(c) $A l > M g > N a$
$M g > A l > N a$

The correct answer is: $M g greater than A l greater than N a$

$M g greater than A l greater than N a$ . This is due to the presence of fully filled s-orbital in Mg.

Which of the following electrons should have the highest value of ionisation energy (for the same value of the principal quantum number)
