A) \[[Ne]\,3{{s}^{2}}3\,{{p}^{3}}\]
B) \[[Ne]\,3{{s}^{2}}3\,{{p}^{2}}\]
C) \[[Ar]\,3{{d}^{10}},\,4{{s}^{2}}4\,{{p}^{3}}\]
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 |
| \[[Ne]\,3{{s}^{2}}3\,{{p}^{3}}\] V |
| \[[Ne]\,3{{s}^{2}}3\,{{p}^{2}}\] IV |
| \[[Ar]\,3{{d}^{10}},\,4{{s}^{2}}4\,{{p}^{3}}\] V |
| \[[Ne]\,3{{s}^{2}}3\,{{p}^{1}}\] III |
| Since IE increases in a period and decreases in |
| a group, \[[Ne]\,3{{s}^{2}}3\,{{p}^{3}}\]configuration has the highest ionisation energy among the given. |
