Highest electron affinity in third period
WebThe amount of energy released when an atom in the gaseous state accepts an electron to form an anion. Factors which affect electron affinity are: Atomic size and Nuclear charge. As atomic radii increases, electron affinity increases. As nuclear charge increases, electron affinity increases. It decreases down a group and increases across a period. WebThe third ionisation energy shows a massive increase because it requires an electron to be removed from magnesium’s second energy level. \[Mg^{2+} (g) \rightarrow ...

Did you know?
The electron affinity (Eea) 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 is not the same as the enthalpy change of electron capture ionization, which is defined as negative when energy is released. In other words, the enthalpy change and the electron affinity … WebQuestion 6: (a) Define the term ‘electron affinity’.
