Subatomic particles are measured in amu's--Atomic Mass units. Protons and neutrons are both approximately 1 amu, and electrons have a mass so much less as to be negligible (about 1/2000 that of a proton).
What else can I help you with?
What are the weights of the subatomic particles?
I think you probably mean the mass of the classical subatomic particles, Proton, Neutron and Electron. From memory, the mass of the proton and neutron are almost the same and approximately 1.6 x 10-24 grams while the mass of an electron is about 0.9 x 10-28 grams. In the Standard Model of subatomic particles, there are very many more particles than these three and their masses are best looked up in tables. Some of the masses of subatomic particles have not yet been determined (neutrinos) and one of the theoretical particles has not yet been shown to exist at this time (Higgs boson).
What galactic formation is made of irregular masses of particles gases and plasmas that reflect light from nearby stars?
nebulae
What sub-atomic particles have a mass of 1 amu?
neutrons and protonsbut NOT electrons (the almost have no mass)
Why was the neutron the last subatomic particle to be discovered?
no electric charge. the nuclear theory at the time explained the atomic masses by assuming the nucleus contained a number of protons equal to the atomic mass number and enough electrons to cancel the charge beyond that of the atomic number of the element.
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.
What statement bout subatomic particles is not true?
"All subatomic particles have the same mass" is not a true statement, as different subatomic particles, such as protons, neutrons, and electrons, have different masses and charges.
What is the subatomic particles mass of 1amu?
The neutron and the proton have masses close to 1 amu.
What are the subatomic particles with no mass called?
Subatomic particles with no mass are called neutrinos. Neutrinos are elementary particles that have extremely small, non-zero masses, but they are considered nearly massless in many calculations due to their very small mass values.
Subatomic particles are closest in mass?
Proton and neutron (components of the atomic nucleus) have masses very close.
How can the subatomic particles be distinguished?
They have different masses, electrical charge, dimensions, life time, spin etc.
Which three subatomic particles are the lightest?
The three lightest subatomic particles are electrons, neutrinos, and photons. Electrons and neutrinos have very small masses, while photons are massless.
How do you spell particles?
That is the correct spelling of the plural noun "particles" (dust, or subatomic masses).
Weight of subatomic particles is measured by?
These masses cannot be measured directly; they are derived by calculation from other physical data.
How do you compare and contrast subatomic particles?
They have different masses, electrical charge, dimensions, life time, spin etc.
What statement best compares the masses of the two samples?
The masses cannot be compared without a balance.
What are the weights of the subatomic particles?
I think you probably mean the mass of the classical subatomic particles, Proton, Neutron and Electron. From memory, the mass of the proton and neutron are almost the same and approximately 1.6 x 10-24 grams while the mass of an electron is about 0.9 x 10-28 grams.

Some of the masses of subatomic particles have not yet been determined (neutrinos) and one of the theoretical particles has not yet been shown to exist at this time (Higgs boson).
What do neutrons and protons have in common?
Neutrons and protons are both subatomic particles found in the nucleus of an atom. They have similar masses and are both composed of smaller particles called quarks.
