What are the subatomic particles with no mass called?
All subatomic particles have mass.
How do you determine sum of subatomic particles?
The mass number is the sum of protons and neutrons in the atomic nucleus.
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 relative atomic mass of subatomic particles in atom?
neutrons are heavier than protons by a bit more than the mass of electron.
What does subatomic particles contribute to the value of atomic mass and atomic number?
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
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
What subatomic particles are added to determine the atomic mass?
Protons and neutrons.
The atomic mass of an element is the weight of what subatomic particles?
The protons and neutrons.

Of the three main subatomic particles the has the least mass?
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or Atomic Mass units.

Which subatomic particles have mass and re included in the calculation of the atomic mass number?
These particles are protons and neutrons; but to be correct the mass of electrons must be added.
