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.
your questions are so unspecific it makes me want to laugh and cry at the same time, what particles?
If you meant to ask about alpha particles, it's a Helium atom with electric charge of +2.
Helium is an element, not a particle.
Helium is an element so it is composed of helium atoms.
it has 2 protons 2 neutrons and two electrons
Helium-3 nucleus has: 1 neutron + 2 protons
The components of neutrons and protons are quarks and gluons.
Protons, which are hydrogen nuclei. Two protons have to be converted to neutrons, as the He nucleus is two protons and two neutrons
Helium particles are Alpha ray's nuclei...
an alpha particle
No the hydrogen nucleus is a proton. The helium nucleus is an alpha particle.
An alpha particle is a helium nucleus; it has a charge of +2.
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).
This is emission of an alpha particle which is a helium nucleus. Thus the atomic number decreases by two and the atomic weight by four, in such a radioactive decay
A particle of alpha radiation is made up of two protons and two neutrons resembling a Helium-4 nucleus.
No the hydrogen nucleus is a proton. The helium nucleus is an alpha particle.
an alpha particle
An alpha particle is a helium nucleus; it has a charge of +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

a He nucleus is known as alpha particle.
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
