Question

write a paragraph on electronic configuration ..word limit 150 words​

Answer 1

Answer:

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.

Explanation:

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.
