ICSE Class 10 Answered

why is energy released in electron affinity?
Asked by Chinmay | 24 Feb, 2015, 06:05: PM
answered-by-expert Expert Answer

Hi,

Energy is required to excite an electron from n = 1 to n = infinity. Because of electrostatic forces between the positively charged nucleus and negatively charged electron.

Conversely, an electron that is added from infinity to its ground state goes from a high energy state to a low energy state. That energy is released.
