Basically, yes... But you should say "the mass". Atomic Mass units are a unit of mass.

Protons and neutrons are formed from quarks.

Why is mass defect important?
E = MC2; energy is equal to a quantity of matter. When protons (and neutrons) combine in an atomic nucleus, the resultant mass is less than that of the individual particles. This is the mass defect, and the 'missing' mass is a result of the energy binding the particles together. The larger the mass defect for a particular atom (isotope), the larger the amount of nuclear binding energy.
What sub-atomic particles have a mass of 1 amu?
neutrons and protonsbut NOT electrons (the almost have no mass)
Why are some objects more dense than other objects?
Some objects are more dense than others due either to the mass of the particles in the material, the atomic number or how closely the particles are packed together. For example, lead, has a high density because its particles have a very high mass. But a material like polystyrene, doesn't have a high density as the particles are spaced far apart and they have a low mass value.
How did the result of gold foil experiment lead Rutherford to recognize the existence of atomic nuclei?
By beaming alpha particles through gold foil and witnessing some of them deflecting, there had to be a mass larger than an alpha particle in the atomic structure. This disproved the plum pudding theory of the atom, as electrons would not have had enough mass to deflect the larger alpha particles.
The first periodic table was arranged by?
Demitri Mendeleev. He arranged it by atomic mass
What is the SI unit used to express the mass of atomic particles?
Dalton Da or amu u

The mass of all particles of an atom added together is its what?
The sum of protons and neutrons in an atom is called mass number.
What do you use atomic mass units for?
The atomic mass unit is 1/12 from the mass of the isotope 12C.
What is the atomic mass of neon'?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, Atomic Mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
Si units used for the masses of atomic particles?
The Si unit used for the masses of particles is the atomic mass unit (amu).
What particles contributing to the atomic mass?
protons and neutrons
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
