The common isotope of Helium ( helium 4 ) contains 4 nucleons - 2 protons and 2 neutrons. Ifyou want to consider the quarks which are believed to make up the nucleons you have 6 up-quarks and 6 down-quarks, for a total of 12. You can't add 12 and 4 to make 16 because that would mean counting the quarks twice. So you have 4 or 12, according to taste. If you want to include gluons or other virtual particles you are on your own. Anyway, a certain Mr.Heisenberg (all right, uncertain) tells us the quicker you can count the more there will be.
Most helium is helium-4. This isotope of helium has two protons and two neutrons in its nucleus, and two electrons in the electron cloud around this nucleus. Helium-3, which has the two protons and only a single neutron in its nucleus within the two-electron cloud, occurs as only about one atom in a million helium atoms. These are the two stable isotopes of helium.
No, the nuclear symbol for helium is "He" and the symbol for a proton is "p". Helium has two protons in its nucleus, along with two neutrons.
The nuclear reaction that results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus is called alpha decay. In this process, an unstable nucleus emits an alpha particle (helium nucleus) which consists of two protons and two neutrons, causing the original nucleus to decrease in atomic number by 2.
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.
An alpha particle consists of two protons and two neutrons, which is the same composition as a helium nucleus. This similarity is why an alpha particle is often referred to as a helium nucleus.
A helium nucleus is an example of an alpha particle, which consists of two protons and two neutrons, essentially the same as a helium-4 nucleus. It is a type of nuclear radiation commonly emitted during radioactive decay.

an alpha particle
A helium nucleus, also known as an alpha particle, is formed during a solar nuclear reaction by the fusion of four hydrogen nuclei.
The nuclear reaction that results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus is called alpha decay. In this process, an unstable nucleus emits an alpha particle (helium nucleus) which consists of two protons and two neutrons, causing the original nucleus to decrease in atomic number by 2.
We give the name alpha decay to this nuclear decay event. The alpha particle, which is a pair of protons and a pair of neutrons bound together, is, in fact a helium-4 nucleus.
An alpha particle is identical to the nucleus of Helium atom
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.
An alpha particle consists of two protons and two neutrons, which is the same composition as a helium nucleus. This similarity is why an alpha particle is often referred to as a helium nucleus.
During a solar nuclear reaction, the type of nucleus formed by the fusion of four nuclei is a helium nucleus, also known as an alpha particle. This process is known as nuclear fusion and is responsible for the energy production in the core of the Sun.
alpha particle
A helium nucleus is an example of an alpha particle, which consists of two protons and two neutrons, essentially the same as a helium-4 nucleus. It is a type of nuclear radiation commonly emitted during radioactive decay.
An alpha particle is equivalent to a helium-4 nucleus, or a helium-4 ion. A difference is that an alpha particle has a certain amount of energy associated with it, so it can said to be fast or hot. The energy is measured in thousands or millions of electron volts (keV or MeV).
