Electron and proton

Electrons and protons in an atom

Electron-and-proton

Electron and proton: All the substances and organisms on the planet are made up of atoms, which are the bedrock of every composition or body known to mankind, and the atom is characterized by its very small size, which is impossible for a human to observe in the abstract. After several studies, scientists in the 19th century described the atomic structure of objects. The atom is made up of a nucleus. The nucleus contains protons and neutrons. There are electrons orbiting the nucleus in regular orbits. It is worth noting that most of the atom’s space is empty. Negative charge.

What is the size of an electron compared to a proton?

The mass of a proton is 1836 times larger than that of an electron, and no study shows the true size of both. The mass can be described by the following mathematical equation:

  • Proton mass: Tsuai proton mass 1.0073 u.
  • The mass of an electron is equal to the mass of an electron 5.486 × 10 ^ -5 u.

Thus, the mass of a proton is about 1836 times the mass of an electron. The difference between can be described by measuring the radius of both them, where the proton radius is 88 × 10 ^ -16 m, while the electron radius is 2.8 × 10 ^ -15 m.

Discovery

The electron was discovered in 1897 by JJ Thomson when he was studying the properties of cathode rays, while the proton was discovered in 1909 by Rutherford when he performed his famous experiment on gold foil.

Whichever is greater, the electron or the proton


The mass of a proton is about 1836 times that of an electron, which means that one mass of a proton is equal to the mass of an 1836 electron.

As for volume, some scientists used the equation of mass and energy equivalence of the world Albert Einstein to calculate the electron radius by default. But modern quantum mechanics has made the assumption that the electron is a wave function and it is difficult to assume its spheres or radius.

In spite of this very large difference between the mass, but each of them carries the same electric charge but with the opposite signal;

Physics has indicated that the electron is a first particle that does not consist of smaller particles. That make up the proton called: (quarks).

Physicists also pointed out that each proton consists of three quarks, and with the rapid scientific progress in our present age is not unlikely to be discovered in the future confirms that these quarks are also composed of finer units.
