why electron gain enthalpy of nitrogen is ZERO?
Answers
Electron gain enthalpy is the energy released when one mole of electrons are added to the isolated gaseous atoms of an element.
Electron gain enthalpy is said to be positive an electron is added to an element
And, it is negative when an electron is removed from the element
Since the electronic configuration of nitrogen is 2s2 2p3, it has a half filled p shell which is a stable configuration. Thus, it has a relatively low tendency to gain or lose electrons and its electron gain enthalpy is zero.
