Electron affinity trend in period 2
WebThe electron affinityof an element is the energy given off when a neutral atom in the gas phase gains an extra electron to form a negatively charged ion. A fluorine atom in the gas phase, for example, gives off energy when it gains an electron to form a fluoride ion. Web19. What trend in electron affinity do you see as you go across a period/row on the periodic table? What causes this trend? Electron affinity increases as you more left to right across a row. The nucleus charge increases so the atomic radius is smaller. Pull from positive nucleus is more important than repulsion from other electrons.
Electron affinity trend in period 2
Did you know?
WebElectron affinity is the energy change that results from adding an electron to a gaseous atom. For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol. Because this value is negative … WebAn element's first ionization energy is the energy required to remove the outermost, or least bound, electron from a neutral atom of the element. On the periodic table, first ionization energy generally increases as you move left to right across a period.
