affinity – The Unconditional Guru

Why the electron affinity or electron gain enthalpy of Chlorine is higher than Fluorine ? Even if Fluorine is most electronegative element.

chlorine shows exceptionally higher electron gain enthalpy than that of florine.

The second electron affinity of oxygen is positive, what does that mean?

Electron affinity is the amount of energy change during the addition of an electron to an isolated gaseous atom. It can be positive as well as negative. Negative electron affinity means that the energy is released during the addition of electron. Which is a favorable condition for gaining an electron. But positive value means thatContinue reading “The second electron affinity of oxygen is positive, what does that mean?”
