why first electron gain enthalpy is negative?
Asked by azeem drabu | 27th Aug, 2011, 03:08: AM
First electron gain enthalpy is not negative always. But it is mostly negative as the protons in the nucleus exert a powerful charge on the electrons and bind them to the atom; so an addition of an electron lets the proton hold on to another electron and hence the strain on the other electrons is reduced. So in general it is negative.
