Question

whenThe electron gain enthalpy of an element is more the energy released is more or less?explain without providing links.

Answer 1

Electron gain enthalpy is the amount of energy that is released when an isolated gaseous atom accepts an electron to become a gaseous anion.

X(g) + e^- → X^-(g) + energy(electron gain enthalpy) ∆H_{electron gain enthalpy​} = negative

Higher the e​lectron gain enthalpy, higher is the tendency of the atom to accept an electron and higher is the energy that is released.
