Today we will review the charge of electron in atoms. The electrical charge is a property of subatomic particles and allows interaction with electromagnetic.
An electrically charged particle is affected by the electromagnetic field and forms an electromagnetic field. The interaction of charge and magnetic field is the source of the electromagnetic force, which is one of the four fundamental forces.
The number of protons and electrons of atoms is equal in normal conditions. In other words, substances not faced with an effect are unloaded. If there is a numerical difference between the number of electrons and the number of protons in some or all of the atoms that make up a substance, it is an electrically charged substance. Charge of electron subject goes on from below.
Charge of electron – Negative and positive load
If the atoms of the matter have lost electrons, they will be positive (+). If atoms have gained electrons, they will be negative (-).
Positive electric ions are called cations. Negative electrified ions are called anions. The load of an object will naturally be equal to the load average of its atoms. Last part of charge of electron article awaits you below.
Experiments about charge of electron
In 1897, Thomson discovered in his cathode ray experiments that the presence of the electron in the atom and the charge-to-mass ratio would always be constant and the same for each element.
In 1908, Millikan, in his experiments with oil droplets known as the “oil drop experiment”, estimated that the smallest load unit was -1,6022 x 106019 C. This is the electrode that carries the load unit.
Oil drop test of Milikan for charge of electron
About ten years after Thomson, Millikan managed to find the charge and then the mass of an electron by means of what is known as the oil-drop experiment. With his discoveries, Millikan received the 1923 Nobel Prize in Physics.
