Second ionization energy of an element is higher than its first ioniza

1.	Second ionization energy of an element is higher than its first ionization energy. Why?
Answer» 1. The energy required to remove an electron from unipositive ion is called second ionisation energy. 2. It is difficult to remove an electron from unipositive ion when compared with neutral atom due to an increase in nuclear attraction. 3. So always second ionisation energy is higher than first ionisation energy.

Answer»

1. The energy required to remove an electron from unipositive ion is called second ionisation energy.

2. It is difficult to remove an electron from unipositive ion when compared with neutral atom due to an increase in nuclear attraction.

3. So always second ionisation energy is higher than first ionisation energy.
