The nucleus of a hydrogen atom, consisting of a single proton, was considered a fundamental particle because it is the simplest atomic nucleus and cannot be divided into smaller components under normal conditions. Protons are classified as baryons, which are fundamental particles made up of quarks, but in the context of hydrogen, the proton serves as a basic building block of matter. Additionally, its properties and role in atomic structure contribute to its status as a fundamental entity in particle physics.
A proton is an elementary particle that is identical to the nucleus of a hydrogen atom. It carries a positive electric charge and accounts for the majority of the mass within an atom.
An alpha particle is identical to B, a helium nucleus. Specifically, it consists of two protons and two neutrons, making it the same as the nucleus of a helium-4 atom.
It is meson. Hideki Yukawa named it mesotron which was later corrected to meson. Muon was the first particle that had the predicted mass of a meson. It was discovered by Carl David Anderson. It was later conclude that it was not the right particle.
A hydrogen atom consists of a proton in its nucleus along with an electron orbiting around it. A proton is a subatomic particle found in the nucleus of an atom and carries a positive charge. In comparison, a hydrogen atom is a neutral particle since it has an equal number of protons and electrons.
The nuclide X would be tritium (hydrogen-3). In the described fusion process, a helium-3 nucleus and tritium combine to form a stable helium-4 nucleus along with the release of an alpha particle (helium-4 nucleus) and a positron.
meson
False. An alpha particle is equivalent to a helium-4 nucleus.
hydrgen nucleus
yrse
No, it is identical to that of a helium atom.
A proton is an elementary particle that is identical to the nucleus of a hydrogen atom. It carries a positive electric charge and accounts for the majority of the mass within an atom.
A single atom of hydrogen-1 is the smallest particle of hydrogen. A hydrogen-1 atom contains only one proton and one electron, and is the simplest atom.
Protons and neutrons are found in the nucleus. While these are theoretically composed of quarks (conversely even more massive particles), quarks do not exist in a free state so are not "fundamental particles" by definition.
When a hydrogen-3 nucleus undergoes radioactive decay, it emits a beta particle (specifically an electron) and an anti-neutrino to transform into helium-3.

Hydrogen usually has no neutrons. However, there is also the heavy hydrogen, a.k.a. deuterium, that has both a proton and a neutron in its nucleus.
A proton is a subatomic particle found in the nucleus of an atom. A hydrogen ion, on the other hand, is a positively charged ion of hydrogen that has lost its electron. So, a hydrogen ion is essentially a proton outside of the nucleus.
