Which of the following should be correct for

{Z_1}

and

{Z_2}

in the following two processes

{M^ + } + {Z_1}\xrightarrow{\,}{M^{2 + }} + {e^ - }

{M^{2 + }} + {Z_2}\xrightarrow{\,}{M^{3 + }} + {e^ - }

View answer and explanation

Correct option: D

{Z_1} < {Z_2}

Option D is correct because the ionization energy increases with each successive ionization, meaning

{Z_2}

(IE2) will always be greater than

{Z_1}

(IE1).
