You will have to tell us what the particle is, but if it is an alpha particle, there are two neutrons in it.
2 protons and 2 neutrons (an a-particle is effectively a helium atom without any electrons).
A nucleon is the amount of protons and neutrons. An alpha particle has an atomic number of 2 and a atomic mass of 4 then it has 2 protons and 2 neutrons.There are 4 nucleons in an alpha particle.
An ALPHA particle may be thought of a a helium nucleus. It contains two protons and two neutrons. An alpha particle is a high speed helium nucleus (He^(2+)).
2 protons and 2 neutrons. An alpha particle is the same as a helium nucleus.
An alpha particle consists of two protons and two neutrons.

An alpha particle is composed of two protons and two neutrons.
