Ernest Rutherford described the existence of the neutron.
Proton or neutron
No, a proton is a positively-charged particle with a mass of 1.673 x 10-27 kg. What you described is a neutron.
Walter Baade and Fritz Zwicky proposed the existence of the neutron star in 1934. Antony Hewish and Samuel Okoye discovered "an unusual source of high radio brightness temperature in the Crab Nebula" in 1965, which turned out to be the Crab Nebula neutron star.
The neutron is a part of the atom, therefore it is smaller.
electron and neutrino are formed by the decay of neutron.
The existence of the neutron was proposed by James Chadwick in 1932. His assumption was based on his experiments involving the bombardment of beryllium with alpha particles, which resulted in the emission of a previously unknown neutral particle that he identified as the neutron.
A sentence for neutron is:A neutron can be described as an uncharged elementary particle
Ernest Rutherford predicted the existence of the neutron, but it was Sir James Chadwick that is credited for the actual discovery of the neutron.
Neutrons have been around since the beginning of the universe, no person created them. Neutrons were first proposed to exist by Earnest Rutherford in 1920, but their existence wasn't verified until 1932 by James Chadwick.
Proton or neutron
They each contain 1 neutron
James Chadwick is given credit for the discovery of the neutron in 1932. Chadwick did experiments to demonstrate the existence of a neutral particle in the nucleus that was later given the name neutron. For this, he received the Nobel Prize in Physics in 1935. Chadwick was not the first person to assert the existence of the neutron, or rather was not the first to assert the existence of a neutral particle in the nucleus with the characteristics of the neutron. Santiago Antunes de Mayolo, a Peruvian scientist, proposed the existence of such a particle as the neutron at the Third Scientific Panamerican Congress in 1924. Ettore Majorana, an Italian theoretical physicist, is credited with make a proposal of the existence of this particle also, but this was not documented in a scientific publication. As with many scientific developments, ideas form over time and with different people. Credit of single person for a single "discovery" is not the same as saying the ideas all evolved from one person. Background on this topic is in the related link and the related questions.
James Chadwick discovered the neutron.
A native from Italy, Enrica Ferni - for demonstrating the existence of radioactive elements produced for neutron irradiation. Enrico Fermi Italy "for his demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by slow neutrons"
The neutron was discovered by Sir James Chadwick in 1932. Chadwick conducted experiments that provided evidence for the existence of a neutral subatomic particle within the atomic nucleus, which he named the neutron.
Yes, Muslims generally believe in the existence of dinosaurs as part of the natural history of the Earth, as described in the Quran and Hadith.
A neutron has a zero electric charge and has a mass slightly greater than that of a proton. A proton and an electron can be fused to create a neutron, and a neutron decays into a proton and an electron (and a bit of something else). More details about the neutron can be had by using the link to the Wikipedia article on this "building block" of the atom.
