WebNov 20, 2024 · Electron affinity of Nitrogen is 7 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. X + e– → X– + energy Affinity = – ∆H. WebDec 19, 2016 · The value of Δ U for the reaction is, in some places, called the "electron affinity". In other places, Δ H for the reaction is called the "electron-gain enthalpy". [1] …

WebFeb 24, 2024 · Assertion (A) : Boron has a smaller first ionisation enthalpy than beryllium. Reason (R) : The penetration of a 2s electron to the nucleus is more than the 2p electron hence 2p electron is more shielded by the inner core of electrons than the 2s electrons. ... Discuss the factors affecting electron gain enthalpy and the trend in its variation ... WebIt feels a greater attractive force, and therefore it takes more energy to pull this electron away from the neutral beryllium atom, and that's the reason for the higher ionization energy. So beryllium has an ionization energy of positive 900 kilojoules per mole, compared to lithium's of 520 kilojoules per mole. halls orange poppy price list
