प्रश्न
Electron affinities of two elements A and B are given below:
A = 3.79 electron volts
B = 3.56 electron volts
Which of them will ionize more easily and why?

उत्तर
Out of A and B, A will ionize more easily to form a negative anion because of the high value of electron affinity, energy released during addition of electron will be high hence the resulting anion formed will be more stable than the corresponding atom.
