WebAug 19, 2024 · The periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their chemical properties. A modern version is shown in Figure 2.1. 1. Most periodic tables provide additional data (such as atomic mass) in a box that contains each element’s symbol. 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 on …
