प्रश्न
Which element from the following has the highest ionization energy?
Explain your choice.
Ne, He, Ar

उत्तर
He
Ionisation energy decreases with an increase in the atomic size, i.e. it decreases as one moves down a group. Ne, He and Ar are inert gases. He - Period 1, Ne - Period 2 and Ar - Period 3.
