WebStep-by-step solution. Step 1 of 3. Electron affinity: electron affinity is the energy change associated with the addition of an electron to a gaseous atom. Elements present in second row of periodic table are Li, Be, B, C, N, O, F and Ne. Li, B, C, O and F can easily accept electrons and release energy, where as Be, B and N have stable ... WebThe reduction of the EA of the first member can be attributed to the small size of the n = 2 shell and the resulting large electron–electron repulsions. For example, chlorine, with an EA value of –348 kJ/mol, has the highest value of any element in the periodic table. The EA of fluorine is –322 kJ/mol.

WebThe electron affinity (EA) is the energy change for the process of adding an electron to a gaseous atom to form an anion (negative ion). X ( g) + e − X − ( g) EA 1. This process can be either endothermic or exothermic, depending on the element. The EA of some of the elements is given in Figure 6.35. WebWhereas while moving down a group in the periodic table, the atomic size increases thereby causing a decrease in the value of electron gain enthalpy. The first electron affinity is always exothermic that is negative. The …

WebMay 22, 2024 · Exothermic Reactions. In nuclear and particle physics the energetics of nuclear reactions is determined by the Q-value of that reaction. The Q-value of the reaction is defined as the difference between the sum of the masses of the initial reactants and the sum of the masses of the final products, in energy units (usually in MeV).

WebThe electron affinity (E ea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion.. X(g) + e − → X − (g) + energy. This differs by sign from the energy change of electron capture ionization. The electron affinity is positive when energy is released … WebAs a result, electron gain enthalpy decreases as the atomic size rises while travelling down a group in the periodic table. Because it is always negative, the initial electron affinities are always exothermic. There will be a positive or endothermic electron affinity …
