WebMar 24, 2024 · The Aufbau principle, simply put, means electrons are added to orbitals as protons are added to an atom. The term comes from the German word "aufbau", which means "built up" or "construction". Lower electron orbitals fill before higher orbitals do, "building up" the electron shell.

WebAntiaromaticity. Antiaromaticity is a chemical property of a cyclic molecule with a π electron system that has higher energy, i.e., it is less stable due to the presence of 4n delocalised (π or lone pair) electrons in it, as opposed to aromaticity. Unlike aromatic compounds, which follow Hückel's rule ( [4 n +2] π electrons) [1] and are ... WebWhat is Electron Affinity?
