A) \[{{F}_{2}}\]
B) \[[Ne]3{{s}^{2}}\,3{{p}^{2}}\]
C) \[{{I}_{2}}\]
D) \[[Ne]\,3{{s}^{2}}\,3{{p}^{1}}\]
Correct Answer: A
Solution :
Key Idea lonisation energy usually increases from left to right in a period with decrease in atomic size and decreases from upto down in a group with increase in atomic size. Electronic configuration Group \[3.0\times {{10}^{5}}\] V \[3.0\times {{10}^{-5}}\] IV \[3.0\times {{10}^{-4}}\] V \[3.0\times {{10}^{4}}\] III Since IE increases in a period and decreases in a group, \[{{H}_{2}}S{{O}_{4}},\]configuration has the highest ionisation energy among the given.You need to login to perform this action.
