Question

can anyone explain me electronic configuration in brief for 9 th class
spammers stay away I will surely report

Answer 1

Answer:

Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus.

Explanation:

For atoms, the notation consists of a sequence of atomic subshell labels (e.g. for phosphorus the sequence 1s, 2s, 2p, 3s, 3p) with the number of electrons assigned to each subshell placed as a superscript. For example, hydrogen has one electron in the s-orbital of the first shell, so its configuration is written 1s1.

Answer 2

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. For example, the electron configuration of sodium is 1s22s22p63s1.

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.
