Hey dear here is ur answer
The first electron affinity isnegative because energy is released in the process of adding one electron to the neutral oxygen atom. ... For the first electron affinity we were adding an electron to a neutral atom, but now we are adding a negative electron to a negative ion so they will repel each other
Hope its help you
