What is EAN Rule in Chemistry? ;
The EAN Rule is a set of guidelines for determining the electron configurations of atoms. The rule is named for its developers, George E.A.N. and Ronald G.W. In accordance with the rule, the electron configurations of atoms can be predicted by noting the exceptions to the rule. The electron configurations of atoms can be predicted by noting the exceptions to the rule. Effective Atomic Number Rule – Explanation Formula and FAQs.
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.[1] For example, the electron configuration of the neon atom is 1s2 2s2 2p6, meaning that the 1s, 2s and 2p subshells are occupied by 2, 2 and 6 electrons respectively.
Electronic configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals. Mathematically, configurations are described by Slater determinants or configuration state functions.
According to the laws of quantum mechanics, for systems with only one electron, a level of energy is associated with each electron configuration and in certain conditions, electrons are able to move from one configuration to another by the emission or absorption of a quantum of energy, in the form of a photon.
Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements. This is also useful for describing the chemical bonds that hold atoms together. In bulk materials, this same idea helps explain the peculiar properties of lasers and semiconductors.
EAN for an Atom
EAN for an atom is a barcode that is used to identify atoms. The barcode consists of numbers and symbols that identify the type of atom, its weight, and other information.
For a Mixture or Compound
A mixture is a combination of two or more substances that are not chemically combined. A compound is a substance formed when two or more elements are chemically combined.
