Q11MAtomic StructureFree sample

Which equation represents the second ionisation energy of an element X?

Options

A   X(g)X2+(g)+2e\text{X(g)} \rightarrow \text{X}^{2+}\text{(g)} + 2\text{e}^-
B   X+(g)X2+(g)+e\text{X}^+\text{(g)} \rightarrow \text{X}^{2+}\text{(g)} + \text{e}^-
C   X(g)+2eX2(g)\text{X(g)} + 2\text{e}^- \rightarrow \text{X}^{2-}\text{(g)}
D   X(g)+eX2(g)\text{X}^-\text{(g)} + \text{e}^- \rightarrow \text{X}^{2-}\text{(g)}
