The difference between electrons and charges is as follows:

1. Different concepts:

Electrons are negatively charged subatomic particles. It can be free (not belonging to any atom), or it can be bound to the nucleus. Electrons in atoms exist in spherical shells of various radii and describing energy levels. The larger the spherical shell, the higher the energy contained in the electrons.

Charge is the positive or negative charge carried by an object or the particles that make up an object. Positively charged particles are called positive charges (symbol " "), and negatively charged particles are called negative charges (symbol " "). for"-"). It is also a property of certain elementary particles (such as electrons and protons) that like charges repel each other and dissimilar charges attract each other.

2. The discoverers are different:

The electron was discovered in 1897 by Joseph John Thomson of the Cavendish Laboratory of Cambridge University while studying cathode rays. Joseph John Thomson proposed the raisin model (date cake model).

Charge is a charge. Around 600 BC, the Greek philosopher Thales recorded that after rubbing cat hair on amber, the amber would attract light objects like feathers. If the friction lasted long enough, it would even A spark appears.

3. Different characteristics:

Electrons are small and light in weight (205 times lighter than muons), and are classified as leptons among subatomic particles. Leptons are elementary particles into which matter is divided. The electron has half spin and satisfies the Fermi condition (according to Fermi-Dirac statistics).

The charge of the electron is about -1.6 - 10-19 Coulomb, and the mass is 9.10956 10-31kg (0.51MeV/c2). It is usually represented by e. The particle with the opposite potential of the electron is called a positron, which has the same mass, spin, and positive charge as the electron. Electrons move around the nucleus. The higher the energy, the farther they are from the orbit of the nucleus

The basic unit of matter that constitutes charge is the atom. An atom is composed of electrons and a nucleus, and the nucleus is composed of protons and neutrons. When an object is uncharged, it has the same number of electrons as it has protons.

There is no charge in nature that exists apart from matter. In an isolated system, no matter what happens, the total number of electrons and protons remains the same, but their combination or position changes, so the charge must be conserved.
