Electron density or electronic density is the measure of the probability of an electron being present at an infinitesimal element of space surrounding any given point. It is a scalar quantity depending upon three spatial variables and is typically denoted as either $${\displaystyle \rho ({\textbf {r}})}$$ See more The electronic density corresponding to a normalised $${\displaystyle N}$$-electron wavefunction $${\displaystyle \Psi }$$ (with $${\displaystyle {\textbf {r}}}$$ and $${\displaystyle s}$$ denoting spatial and spin variables … See more From its definition, the electron density is a non-negative function integrating to the total number of electrons. Further, for a system with kinetic energy T, the density satisfies the inequalities See more In molecules, regions of large electron density are usually found around the atom, and its bonds.
