All of them to a certain extent.
protons and neutrons
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
Neutrons and protons have masses approximative equal to one amu.

Atomic Mass Unit (amu)
Atomic mass unit
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
The Si unit used for the masses of particles is the atomic mass unit (amu).
protons and neutrons
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
These particles are protons and neutrons; but to be correct the mass of electrons must be added.
