No two subatomic particles have the exact same mass. The proton and the neutron, however, come close. Neutrons are heavier than protons by only 2.3 X 10-30 kg.

What two particles of the atom are added together to get the atomic mass?
4
What particle or particles carry virtually all the mass (weight) of any atom?
Virtually all of the mass of an atom is carried by the proton and the neutron. The electron has very, very little mass relative to these two particles.
Which two subatomic particles make up the atomic weight of an atom of an element?
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
What are the two principal components of the nucleus of the atom?
The two principal components of an atom at a subatomic level are Protons and Neutrons. Protons are subatomic particles with a mass of 1 and a charge of 1+ Neutrons are subatomic particles with a mass of 1 and a charge of 0 or neutral
What two subatomic have about the same mass?
These particles are: proton and neutron.
What two particles in an atom have approximatley the same mass?
Proton and neutron.
What two atomic particles are in the nucleus of an atom?
Protons and neutrons are the two particles that are in the nucleus of an atom. Electrons orbit around the atom
What are the two particles that makeup the mass of an atom?
protons and neutrons

What are the two subatomic particles with a mass?
In the atom, protons and neutrons; the mass of the electron is very small.
What particle or particles carry virtually all the mass (weight) of any atom?
Virtually all of the mass of an atom is carried by the proton and the neutron. The electron has very, very little mass relative to these two particles.
What are the same number of these two particles in an atom?
Protons and electrons.
Which two subatomic particles make up the atomic weight of an atom of an element?
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What are the two principal components of the nucleus of the atom?
The two principal components of an atom at a subatomic level are Protons and Neutrons. Protons are subatomic particles with a mass of 1 and a charge of 1+ Neutrons are subatomic particles with a mass of 1 and a charge of 0 or neutral
