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

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.
What is the mass number to boron 10?
Boron is a metal element. Atomic mass of it is 11.
What is the SI unit used to express the mass of atomic particles?
Dalton Da or amu u
What is 1amu?
1 amu (atomic mass unit) is a unit of mass equal to one twelfth of the mass of a carbon-12 atom. It is used to express the mass of atomic and subatomic particles.
What is the SI unit that is used to express the mass of atomic particles?
The SI unit is the unified atomic mass unit (amu), the symbol is u. Or Dalton, the symbol is Da.
What is the atomic mass unit of protons and neutrons?
The atomic mass unit of protons and neutrons is approximately 1.67 x 10^-27 kg. This unit is used to express the mass of subatomic particles in atomic physics.
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.
Why do scientists express atomic mass in atomic mass units?
Scientists express atomic mass in atomic mass units (amu) to provide a standardized way to compare the masses of atoms and molecules on a scale that is convenient for the size of subatomic particles. One atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom, making it easier to express and calculate the relative masses of different elements. Using amu allows for clearer communication in scientific literature and simplifies calculations in chemistry and physics.
What is the difference between atomic mass and atomic mass unit?
The atomic mass unit is used to express the measure of the atomic mass.
What is the mass of the atom is so small that there is a measure calles the atomic?
The mass of an atom is so small that there is a unit called the atomic mass unit (amu) used to express it. One atomic mass unit is roughly equal to the mass of a proton or neutron, which are the subatomic particles found in the nucleus of an atom. This unit is convenient for expressing the mass of atoms without dealing with very small numbers.
What is the unit for the mass of atomic particles?
Atomic Mass Unit (amu)
What is the unit of measurement use for atomic particles?
Atomic mass unit
Do carbon and oxygen have the same atomic mass?
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.
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) .
