Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
The neutral particle of an atom weighing approximately one atomic mass unit?
This atomic particle is the neutron.
Which atomic particle has no mass?
Photons and neutrinos dont have mass.
