The element with positive electron gain enthalpy is |
|
Answer» Electron gain enthalpy is defined as the energy released when one mole of electron are added to the gaseous state in an atom. The more the TENDENCY of an element to gain electron, its electron gain enthalpy will be more negative The elements which have no tendency to gain electrons have POSITIVE electron gain enthalpies LIKE all noble gases like Ne have fully FILLED outer SHELL thus its electron gain enthalpy is positive |
