Identify the element having lowest first ionization enthalpy?

(A)PoCorrect
(B)Te
(C)Br
(D)Kr

Answer: (A)

Solution

Ionisation enthalpy decreases down a group (larger atomic size, greater shielding) and increases across a period (higher effective nuclear charge). Po and Te are in group 16 with Po below Te, so IE_1(Po)$} ≈ 812 <
