electron affinity value increase from nitrogen to flourine in the periodic table. explain giving reason?
Answers
Answer:
Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.
Explanation:
Electron affinity (EA) or electron gain enthalpy or simply affinity in the periodic table defines the amount of energy released when an electron is added to an isolated neutral gaseous atom in its lowest energy level (ground state) to produce an anion. In ionization energy, energy is supplied to remove one or more electrons from an atom or a cation. In electron affinity, the energy is released with the addition of one or more electrons in an atom or anion.
