Electron Configuration of Hg(1-)
The Hg(1-) anion is formed by the addition of one electron to the neutral mercury atom. This extra electron must occupy the available subshells according to established principles of atomic structure. This involves filling the available orbitals in order of increasing energy levels. The process is governed by Hund’s rule, which dictates that electrons will singly occupy orbitals of the same energy before doubling up.
Electron Filling Process
The filling of subshells proceeds systematically, following the Aufbau principle, which dictates that electrons first occupy the lowest energy levels available. This principle, coupled with Hund’s rule, ensures the most stable electronic configuration. For example, the 6s subshell fills before the 4f subshells.
Principles Governing Electron Distribution
Several fundamental principles govern the distribution of electrons within an atom’s subshells. The Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers. This is crucial in determining the maximum number of electrons that can occupy each subshell. The Aufbau principle, as mentioned, dictates that electrons fill lower energy levels first, while Hund’s rule dictates that electrons will individually occupy each orbital within a subshell before pairing up.
These principles collectively determine the unique electron configuration of each element, including Mercury.
