Can you use the atomic number and atomic mass to calculate the number of each subatomic particle?

atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons


What atomic mass does a beta particle have?

A beta particle, which can be either an electron (β-) or a positron (β+), has a very small atomic mass of approximately 0.00054858 atomic mass units (amu) for an electron. This is significantly less than the atomic masses of protons and neutrons, which are about 1 amu each. In practical terms, the mass of a beta particle is often considered negligible compared to nucleons in atomic nuclei.
