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.
Four. Two protons and two neutrons.

Neutrons
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.
A neutron is a subatomic particle with no charge.
The nucleus is made of protons and neutrons.
Neutrons are "neutral;" they have no charge.
