Question

Write about 'Electronic configuration of the elements'​

Answer 1

Explanation:

The electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence.

Answer 2

Answer

ELECTRON CONFIGURATION

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.

Electron Configurations are useful for:

• Determining the valency of an element.

• Predicting the properties of a group of elements (elements with similar electron configurations tend to exhibit similar properties).
• Interpreting atomic spectra.

This notation for the distribution of electrons in the atomic orbitals of atoms came into practice shortly after the Bohr model of the atom was presented by Ernest Rutherford and Niels Bohr in the year 1913.
