What is Proton ?

hi

Protons are located in the nucleus of atoms, together with any neutrons also present in the atom. Protons have a positive (+1) charge, which balances the negative (-1) charge of the electrons that surround the nuclei of atoms. Protons have a relative mass of 1, which is the same as the relative mass of neutrons.

Proton has been providing the humble denizens of Malaysia with quality rides for the past 3 decades. The brainchild of our PM Tun Dr Mahathir Mohamad, Proton was conceptualised to show the world what Malaysia had to offer – while simultaneously boosting our industrial capabilities.

Proton is short for Perusahaan Otomobil Nasional, which roughly translates to national automotive enterprise/company.

Proton succeeded extreme heat and cold tests in Oman deserts and the North and South Poles. This proves that Proton cars have the extraordinary ability to perform under extreme temperatures.

Proton, elementary particle having a single positive electrical charge and constituting the nucleus of the ordinary hydrogen atom.

The positive charge of the nucleus of any atom is due to its protons. Every atomic nucleus contains one or more protons; the number of protons, called the atomic number, is different for every element (see periodic table).

The mass of the proton is about 1,840 times the mass of the electron and slightly less than the mass of the neutron. The total number of nucleons, as protons and neutrons are collectively called, in any nucleus is the mass number of the nucleus.

The existence of the nucleus was postulated by Ernest Rutherford in 1911 to explain his experiments on the scattering of alpha particles; in 1919 he discovered the proton as a product of the disintegration of the atomic nucleus.

The proton and the neutron are regarded as two aspects or states of a single entity, the nucleon. The proton is the lightest of the baryon class of elementary particles. The proton and other baryons are composed of triplets of the elementary particle called the quark.

A proton, for instance, consists of two quarks called up and one quark called down, a neutron consists of two down quarks and an up quark. The antiparticle of the proton, the antiproton, was discovered in 1955; it has the same mass as the proton but a unit negative charge and opposite magnetic moment.

Protons are frequently used in a particle accelerator as either the bombarding (accelerated) particle, the target nucleus, or both. The possibility that the proton may have a finite lifetime has recently come under examination.

If the proton does indeed decay into lighter products, however, it takes an extremely long time to do so; experimental evidence suggests that the proton has a lifetime of at least 1031 years.

Proton (symbol p) Stable elementary particle with a positive charge equal in magnitude to the negative charge of the electron. The proton was discovered (1919) by Ernest Rutherford.

It forms the nucleus of the lightest isotope of hydrogen and, with the neutron, is a constituent of the nuclei of all other elements. It is made up of three quarks. The proton is a baryon with a mass c.1836 times heavier than the electron.

The number of protons in the nucleus of an element is equal to its atomic number. Protons also occur in primary cosmic radiation. Beams of high-velocity protons, produced by particle accelerator, are used to study nuclear reactions. See also particle physics.

The proton is a positively charged subatomic particle. Protons are one of the fundamental constituents of all atoms. Protons, in addition to neutrons, are found in a very concentrated region of space within atoms referred to as the nucleus.

The discovery of the proton, neutron, and electron revolutionized the way scientists viewed the atom. Recent research has shown that protons are themselves made up of even smaller particles called quarks and gluons.

Early atomic theory assumed that atoms were indivisible. However, when English physicist and chemist Michael Faraday (1791–1867) demonstrated, in 1834, that chemical elements were electrical in nature, scientists embarked on a series of experiments that challenged, and eventually demolished, the fundamental assumptions of traditional atomic theory.

For example, in 1878, British chemist and physicist Sir William Crookes (1832–1919), who predicted the discovery of isotopes, started experimenting with cathode rays, which occurred when electricity was discharged between two metal plates in a tube (later named a Crookes tube) with gas at an extremely low pressure.

Further experiments led to the discovery of protons. For example, when scientists drilled holes in the positively charged (anode) plate of the Crookes tube, they detected rays moving in the opposite direction (from the anode to the negatively charged cathode) of the cathode rays.

Named canal rays, these rays were studied by German physicist Wilhelm Wien (1864– 1928). In 1905, Wien identified some of these rays are hydrogen ions. Researchers later established that rays with the least mass were protons.

A proton is found to consist of two up quarks, each with a +2/3 electric charge, and one down quark, with a -1/3 electric charge. The individual quarks are held together by particles called gluons.

Recent research has revealed the possibility of an even deeper substructure, and further work could lead to new theories that may overturn the current model of the proton’s structure. Scientists are continuing to use high-energy beams from within particle accelerators to discover more complex information about protons.
