Tiếng ViệtIn the engineering system, in order to obtain an electromagnetic field, or a magnetic field or an electric field, a property of an atom is born that is charge. So what is electric charge and what types does it have?

What is electric charge, point charge?
Electricity
The electric charge TTTT is a fundamental property of some atomic particles, which is characteristic for the electromagnetic interactions between those particles. Charges generate electromagnetic fields and are also influenced by electromagnetic fields. The interaction between an electric charge and the electromagnetic field, when it is moving or at rest relative to the electromagnetic field, causes the electromagnetic force, one of the fundamental forces of nature. So how many types of electric charge are there?
Currently, in reality, electric charges exist around us such as: bodies, water, earth, metals, objects, etc. However, there are still objects that do not have an electrical charge called intermediates. From a scientific point of view, it is defined by the number of electrons, nucleus, and charge per electron.
What is point charge ?
The charge generated from small charged lattice particles, such as a point substance, is called a point charge. A point charge is a charge carrier, much smaller in size than the distance to the point you are considering. More specifically a point charge is a charge that is considered to be concentrated at a point.
What is point charge? If an object is very small in size compared to the distance to the point we consider, the charged object can be considered as a point accumulation or point charge.

Conservation of charge and how many types of charge?
How many types of electric charge are there? There are two types of electric charge. Objects with a charge of the same sign repel each other, and objects with a different charge attract each other. There are currently two types of electric charge, positive (+) and negative (-). Two negative (-) or (+) charges will repel each other, while (-) and positive (+) charges will attract each other.
The method of conservation of charge states that the total positive charge is always equal to the total negative charge, in other words the total number of protons is equal to the number of electrons in an atom. We can calculate that in solution the total number of moles times the positive charge will be equal to the number of moles times the negative charge.
Nuclear charge, electron, proton
Nuclear charge consists of protons and neutrons. If the nucleus has n protons, the charge of the nucleus is equal to n and the number of neutrons. An atom is electrically neutral, so it has the same number of protons in its nucleus as the atom’s number of electrons. It can be seen that the number of nuclear charges n = number of protons = number of electrons.
Electron charge is a particle of electrical charge in an atom, which has a negative (-) charge. Electrons are located on the outside of an atom and must have the same number of protons to obtain an electrically neutral atom. Electrons play a fundamental role in physical phenomena such as electricity, magnetism, chemistry and conductivity. In addition, electrons are capable of electric and magnetic fields.
Charge proton is an electrically charged particle of an atom, proton carries a positive charge (+). Protons are located in the nucleus of an atom along with neutrons and the number of protons is equal to the number of electrons outside the atom to obtain an electrically neutral atom. the nature of a proton is made up of 3 quarks (2 up quarks and 1 down quark).
