How to write electronic nitrogen?

The electronegativity of nitrogen 5 ion is shown in the following figure.

For the sake of simplicity, a cross "×" is often used around the symbol of elements in chemistry to represent the outermost electrons of element atoms. The expression of this substance is called electron.

The classical 8-angle electron theory in middle school belongs to outdated theory, which can only be used to represent the substances formed by a few main group elements, but not the substances formed by transition elements, and can not correctly represent the structures of many common substances.

Electronically, it can represent atoms, ions and simple molecules, as well as valence compounds, ionic compounds and their formation processes.

According to the number of electrons in the outermost layer of an element atom, symbols such as ""(or "×") are used to represent 1 electrons on the element symbol, and the redundant electrons are paired.

Write electronic notes

1. No matter what kind of particles, their electronic morphology is composed of atoms as the basic unit, and it is impossible to have angle codes or even coefficients.

2. The electronegativity of atoms constituting various particles must be uniform and symmetrical. A stable 8-electron structure is usually represented by four pairs of electrons (usually one pair of electrons at the top, bottom, left and right of the element symbol).

3. The classical 8-angle electron in middle school is an outdated theory, which can only be used to represent the substances formed by a small number of main group elements, but not the substances formed by transition group elements.
