When a beta particle is emitted does the mass number of the isotope remains unchanged?

With the ejection of a beta particle (electron), there is a minute loss of mass. Electrons have very low mass. The atomic number increases though as a neutron is transformed into a proton. A antineutrino is also ejected.
In a similar process, positron emission also called beta decay,- a positron is emitted and a proton is transformed into a neutron, the atomic number decreases. A neutrino is also ejected.

One quarter.
What happens when aluminium is heated?
It would evaporate the water, form salts, then evaporate completely
Is candle wax melting chemical or physical change?
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
When a beta particle is emitted the mass number of a necleus are?
It remains unchanged. By the way, the spelling is "nucleus", not "necleus".
When iron 59 undergoes beta decay what is the results?
The daughter product in this nuclear process will be cobalt-59, which is stable. One neutron becomes a proton and an electron. The proton remains, adding 1 to the nuclide's atomic number; the electron is emitted as a beta particle.
Does the beta particle increase or decrase mass?
Mass remains unchanged, the only thing is that there is increases or decreases of the positive charge of the original nucleus by one unit.
What is a variable that remains unchanged?
A constant
If a current passed in spring then?
remains unchanged
What isotopes remains after the alpha decay of uranium-238?
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.

What is a condition which remains constant or unchanged in an experiment?
yes queen
Which type of character remains essentially unchanged throughout the action of a stor?
A static character remains essentially unchanged throughout the action of a story. They typically do not undergo significant development or transformation.
What happend to the atomic number of an element which emits alpha particle and two beta particle?
THe atomic number would decrease by 2 as alpha particle comes out. But for two beta particles the atomic number would increase by 2. So the atomic number remains unchanged due to emission of one alpha followed by 2 beta particles.
Is when it remains unchanged in the presence of nitrogen chemical or physical?
When something remains unchanged in the presence of nitrogen is it a physical change?
What isotope remains after the alpha decay of polonium 212?
Polonium 212 has 84 protons and 128 neutrons. An alpha particle is 2 protons and 2 neutrons, so the daughter nucleus will have 82 protons and 126 neutrons, making it lead 208.
