In chemistry, understanding how atoms gain or lose electrons is key to predicting chemical behavior. One important property in this context is electron affinity (EA)—the amount of energy released or absorbed when an atom gains an electron. It plays a crucial role in explaining why certain elements form negative ions, how elements behave in reactions, and the overall trends in the periodic table. This article explains what electron affinity(EA) is, how it works, why it varies among elements, and how it influences chemical bonding and reactivity. What Is Electron Affinity (EA)? What is Electron Affinity (EA)? Eureka Technical Q&A explains…

But just a few years later, they all but disappeared. So what happened? This article explores how 3D TVs worked, the different types of 3D technology, why consumers lost interest, and whether the format has a future in the age of 4K and virtual reality. How Did 3D TVs Work? Curious about 3D TVs? Eureka Technical Q&A explains how they create depth perception using stereoscopic technology,…
In chemistry, knowing the maximum amount of product that a reaction can theoretically produce is essential for planning, scaling, and improving lab processes. This maximum output is known as the theoretical yield. Accurately calculating it helps chemists evaluate reaction efficiency, identify losses, and compare actual yield against expectations. This guide will explain how to calculate theoretical yield in a clear, step-by-step format, while also introducing how PatSnap Eureka can enhance the process with data-driven support. What Is Theoretical Yield? What is Surface Plasmon Resonance (SPR)? Eureka Technical Q&A explains that SPR is a powerful optical technique used to detect molecular…
