Question

what is electronic configuration​

Answer 1

Answer:

The electronic configuration is the regular distribution of electrons in the various atomic orbitals.

Up to seven levels of energy, commonly known as energy orbitals, can be discovered around the nucleus, numbered from 1 to 7. Each of these seven levels can be further broken into four sublevels, which are designated by the letters s, p, d, and f.

The greater the energy level of an electron, the further it orbits from the nucleus. Meaning hereby, electrons in an electronic shell far from the nucleus have a greater energy level than electrons in electronic shells closer to the nucleus.

According to its electronic configuration, an atom can form specific chemical bonds.

Sublevel s, for example, can only have two electrons at most, whereas sublevel p can only have six.

Electronic Configuration:

• In atomic physics and  quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecules in atomic or molecular orbitals. This is also useful for describing the chemical bonds that hold atoms together.

• For example, the electron configuration of the neon atoms is 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, absorption of a quantum of energy, in the form of a photon.

• The most widespread application of electron configurations is in the rationalization of chemical properties, in both organic and inorganic chemistry.
