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. WebWrite an equation for the first electron affinity of helium. Would you predict a positive or a negative energy... If the electron affinity for an element is a negative number, does it mean that the anion of the element is mo...

WebSep 14, 2024 · Electron affinity is the energy change when an electron is added to an atom to form an anion (negatively charged ion). Generally, electrons tend to repel one another. … WebElectron affinity (the energy associated with forming an anion) is more favorable (exothermic) when electrons are placed into lower energy orbitals, closer to the nucleus. Therefore, electron affinity becomes increasingly negative as we move left to right across the periodic table and decreases as we move down a group.
WebElectron affinity generally increases in magnitude as we move to the right across a period (row) in the periodic table (across a period). There is not a definitive trend as you go down a group (column) on the periodic table; sometimes electron affinity increases, sometimes it decreases. Figure 3.
