Electron gain enthalphy is the amount of energy involved when an isolated gaseous atom accepts an electron to form a monovalent anion the value of the electron gain enthalpy of halogens are given below: F : -328 KJ mol^(-1) Cl - 349 KJ mol^(-1) Br : -325 KJ mol^(-1) I : -295 KJ mol^(-1)Chlorine has more negative electron gain enthalpy than fluorine. why ?

Electron gain enthalphy is the amount of energy involved when an isolated gaseous atom accepts an electron to form a monovalent anion the value of the electron gain enthalpy of halogens are given below: F : -328 KJ mol^(-1) Cl - 349 KJ mol^(-1) Br : -325 KJ mol^(-1) I : -295 KJ mol^(-1) Why the negative electron gain enthalpy decreases from chlorine iodine?

Ionisation energy of F^Ɵ is 320 kJ mol^(-1) . The electron gain enthalpy of fluorine would be

Generally electron gain enthalpy increases along a period and decreases down the group. But electron gain enthalpy of oxygen is -141 kJ//mol while that of sulphur is -200 kJ//mol . Explain.

Calculate the energy needed to convert three moles of sodium atoms in the gaseous state to sodium ions, The ionization energy of sodium is 495 kJ mol^(-1)

The enthalpy of formation of NaCl(s) is -411.2 kJ mol^(-1). The enthalpy of sublimation of Na(s), its ionization enthalpy in the gaseous state, the bond energy of chlorine, its electron gain enthalpy are 108.4, 495.6, 242 and -348.6 kJ mol^(-1) respectively. The energy required to break one mole of solid sodium chloride into its ions in the gaseous state is (in kJ)
