1 Medium
1 of 1
Analyzing +4 | -1
The first second and third ionisation energies (E1,E2  and  E3)\left( {{E_1},{E_2}\,\,and\,\,{E_3}} \right) for an element are 7  eV,12.5  eV7\,\,eV,12.5\,\,eV and 42.5  eV42.5\,\,eV respectively. The most stable oxidation state of the element will be
View answer and explanation
Correct option: D
+2+ 2
Option D (+2) is correct because there is a large jump in ionization energy between E2 and E3, indicating that the element readily loses two electrons to achieve a stable configuration.
