Matter is made up of molecules, which are made up of atoms with negatively charged electrons and positively charged protons. Under normal circumstances, the number of protons in an atom is the same as the number of electrons, which is in positive negative balance, so it appears to be electrically neutral. However, when electrons are coiled around the atomic nucleus, they will break away from the track and invade other atoms B as soon as an external force is applied. Atom A has a positive image due to the short number of electrons, which is called cation. Atom B has a negative image due to the increased number of electrons, which is called anion.

The reason for the formation of the unbalanced electron dispersion is that the electron breaks away from the track due to an external force, which includes various energies (such as kinetic energy, potential energy, thermal energy, chemical energy, etc.). In ordinary days, any two objects with different materials touch each other and then leave each other, static electricity can occur.

When two different objects touch each other, one object will lose some charge, for example, the electron will be transferred to another object to make it positively charged, while the other individual will get some objects with remaining electrons and become negatively charged. If the charge is difficult to neutralize in the process of separation, the charge will accumulate and cause the object to carry static electricity. Therefore, objects will be charged with static electricity after touching other objects. Generally, when a piece of plastic film is peeled off from an object, it is a typical "touch separation" electrification. In ordinary days, the static electricity that occurs when undressing is also a "touch separation" electrification.

Solids, liquids, and even gases can carry static electricity by touching them. Why do gases also have static electricity? As the gas is also composed of molecules and atoms, when the air is active, molecules and atoms will also have a "touch separation" and become electrified. Therefore, there will be different levels of static electricity in our surroundings and even in our bodies. When static electricity accumulates to a certain extent, it will discharge.

We all know that conflicts are electrified and there are few rumors of touching electrification. In essence, conflict electrification is a process of touching and parting to form the imbalance of positive and negative charges. Conflict is a process of constant touch and separation. Therefore, impulse electrification is essentially touch electrification. In ordinary days, all kinds of objects may have static electricity due to movement or conflict. Work desk, floor, chair, clothes, paper, files, packaging materials, active air.

Another common electrification is inductive electrification. When a charged object is close to an uncharged object, negative and positive electricity will be induced at both ends of the uncharged conductor.

Other electrification methods include thermoelectric and piezoelectric electrification, Helmholtz layer, eruption electrification, etc
