The static electricity disaster is terrible~~~ Then how did the ''static'' come from??
Generally speaking, matter is composed of atomic tiny particles, and among atoms, there are neutrons, electrons, and protons.
Under normal circumstances, the number of protons and electrons in an atom is equal (that is, the number of positive and negative charges is equal), so the atom is electrically neutral.
When an atom loses its outer electrons, the atom is positively charged with more protons than electrons.
When an atom gains foreign electrons, the number of protons is less than the number of electrons, and the atom is negatively charged.

The structure of electrons and matter
Balance of Charge : Number of Electrons = Number of Protons
Positively charged : number of electrons < number of protons
Negatively charged : number of electrons > number of protons
* Just change the number of electrons to electrify matter
Suppose there is a rod with 10,000 atoms, each atom has 2 neutrons and 2 electrons

Neutral atoms can cause electrons to move due to friction, contact or peeling.
Triboelectric electrification: When two objects are in contact with each other, they will be electrified due to the friction between the contact surfaces.
Stripping electrification: Electron movement generated when stripping is performed. The faster the peeling speed, the greater the charge amount.
Rolling electrification: Two objects are electrified by repeated contact.
Jet electrification: When the high-pressure gas or liquid is ejected, it will be electrified by friction with the nozzle.
And what determines the amount of electricity (static electricity)?
Contact area: The larger the area, the more static electricity is generated.
Pressure: The higher the pressure, the greater the amount of static electricity generated.
Friction: The greater the friction, the greater the amount of static electricity generated.
Temperature: Although there is no special effect, the higher the temperature, the smaller the value of the electric group.
Humidity: The higher the humidity, the less static electricity is generated.
