Question

Why ie2 is greater than ie1. Deifine ie1 and ie2

Answer 1

Answer:

hey here is your answer

ionisation energy or ionisation enthalpy is the enrgy required to remove the most loosely bound electron from an isolated gaseous atom . and IE1 , IE2 , these are the removal of first as well as second electron from an atom . ... the second ionisation energy is always more than that of first ionisation energy .

hope it help you ☺️

Answer 2

$I.E_2$ > $I.E_1$ as more energy is need to remove second electron as now electron is to removed from a posiively charged ion.

Explanation:

The ionization energy is the energy required to remove an electron from the valence shell of an isolated gaseous atom of an element.

$I.E_1$ is the energy required to remove first electron from the valence shell of an isolated gaseous atom of an element.

$M\rightarrow M^++e^-$

$I.E_2$ is the energy required to remove second electron from the valence shell of positively charged gaseous atom of an element.

$M^+\rightarrow M^{2+}+e^-$

$I.E_2$ > $I.E_1$ as more energy is need to remove second electron as now electron is to removed from a positively charged ion. Thus there is more attraction of electron towards the positively charged ion and thus more energy is required.
