WebJun 25, 2015 · This is a difficult question to answer. Following the Aufbau Principle and the n+l rule, the 4s orbital should fill before the 3d orbital. So why is 3d lower in energy? In short, the Aufbau Principle is not entirely … In statistical mechanics, the radial distribution function, (or pair correlation function) in a system of particles (atoms, molecules, colloids, etc.), describes how density varies as a function of distance from a reference particle. If a given particle is taken to be at the origin O, and if is the average number density of particles, then the local time-averaged density at a distance from O is . …

WebFor s -orbitals, the radial distribution function is given by multiplying the electron density by 4π r2. By definition, it is independent of direction. In the case of the hydrogen atom, the maximum value of the radial distribution function corresponds to r = 1 AU, 52.9 pm.
