Question

if successive ionisation potential of an atom is 60eV,80eV,230eV,270eV ,then how many electron are present in outermost shell of atom?

2
3
4
5​

Answer 1

Answer:

As the difference between I 3 and I 4 is maximum, so the element (X) has three valence electrons as after losing three electrons, it acquires stable inert gas configuration.

Answer 2

Answer:

Thanks for your question

Your required answer :

• As in the question it is given that successive ionisation potential of an atom is 60eV,80eV,230eV,270e.
• So from this we can easily know the answer is 3
