Atomic orbital - Wikipedia. The shapes of the first five atomic orbitals are: 1s, 2s, 2p x, 2p y, and 2p z. The two colors show the phase or sign of the wave function in each region. Each picture is domain coloring of a ψ (x, y, z) function which depends on the coordinates of one electron.
21 kwi 2022 · Methods for separately examining the radial portions of atomic orbitals provide useful information about the distribution of charge density within the orbitals. Graphs of the radial functions, \(R(r)\), for the 1s, 2s, and 2p orbitals plotted in Figure \(\PageIndex{2}\).
Examine the electron density plots to see how the electron density increases exponentially towards the nucleus. The shape of the 1 s orbital. While still spherical, the higher s -orbitals ( 2 s , 3 s , 4 s , 5 s , 6 s , and 7 s ) are more complex since they have spherical nodes.
For example, in the ground state of the hydrogen atom, the single electron is in the 1s orbital, whereas in the first excited state, the atom has absorbed energy and the electron has been promoted to one of the n = 2 orbitals.
One way of representing electron probability distributions is \(Ψ^2\). Because \(Ψ^2\) gives the probability of finding an electron in a given volume of space (such as a cubic picometer), a plot of \(Ψ^2\) versus distance from the nucleus (\(r\)) is a plot of the probability density.
This page shows representations of electron density using two-dimensional and three-dimensional electron "dot-density" diagrams. High density of dots in a region denotes high electron density. The two-dimensional plot is across a plane of the 1 s orbital.
