The electron configuration of scandium asġ 2 2 3 3 4 3 s s p s p s d Īnd other scientists choose to write the electron configuration of scandium asġ 2 2 3 3 3 4. We canĪppreciate the different conventions by considering the electron configuration of scandium. There are two common conventions for writing the electron configurations of the period four transition elements. They have electron configurations that are made up of just seven subshell labels. The period four transition metal elements have the simplest electron configurations of all theĭifferent types of transition metal elements.
COPPER TRANSITION METAL SERIES
The electron configuration of an element is a series of baseline and superscript symbols that describes the distribution ofĮlectrons in atomic orbitals. For example, the 4s atomic orbital tends to be filled before the 3d atomic orbital because the 4s atomic orbital has the lower energy value. Some atomic orbitals with relatively high principal quantum numbers have to be filled before other atomic orbitals that have lower principal quantum numbers. The energy-level diagram can also be used to infer that the filling order is not straightforward. The energy-level diagram can be used to understand that electrons will always fill the 1s subshell before they start to fill the 2s subshell and that the 2p subshell will always be filled after the 2s subshell. The Aufbau Principle states that electrons fill the lowest energy atomic orbitals before they fill higher energy atomic orbitals.
