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.

If an isotope undergoes beta emission?
If an isotope undergoes beta emission, a neutron in the nucleus is transformed into a proton, along with the emission of a beta particle (an electron) and an antineutrino. This process increases the atomic number of the nucleus by one but leaves the mass number unchanged.
Is when it remains unchanged in the presence of nitrogen chemical or physical?
When a substance remains unchanged in the presence of nitrogen, it is likely due to its chemical inertness to nitrogen. This can be a result of the substance's molecular structure or its lack of reactivity with nitrogen molecules. Physical properties, such as solubility or vapor pressure, can also play a role in determining whether a substance remains unchanged in the presence of nitrogen.
How much of an original isotope remains at the end of a second half-life?
At the end of a second half-life, one-fourth (25%) of the original isotope remains. This is because each half-life halves the amount of the isotope present.
Is the catalyst consumed in the reaction process?
In a chemical reaction, a catalyst is not consumed and remains unchanged at the end of the reaction process.
What happens to an enzyme after a biochemical reaction?
After a biochemical reaction, an enzyme typically remains unchanged and can be reused in other reactions.
When a beta particle is emitted the mass number of a necleus are?
When a beta particle is emitted, the mass number of the nucleus remains the same. The mass number is the total number of protons and neutrons in the nucleus, and beta decay involves the transformation of a neutron into a proton, which does not affect the total number of nucleons in the nucleus.
Does the beta particle increase or decrase mass?
The beta particle decreases mass because it is an electron emitted from a nucleus during beta decay. The process of emitting a beta particle can result in the conversion of a neutron into a proton, leading to a decrease in the mass number of the nucleus.
If an isotope undergoes beta emission?
If an isotope undergoes beta emission, a neutron in the nucleus is transformed into a proton, along with the emission of a beta particle (an electron) and an antineutrino. This process increases the atomic number of the nucleus by one but leaves the mass number unchanged.
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.
When a charged particle enters in a uniform magnetic field then its kinetic energy ..becomes?
When a charged particle enters a uniform magnetic field, its kinetic energy remains constant. This is because the magnetic field exerts a force perpendicular to the particle's velocity, which changes the direction of the particle's motion but does not work on it. As a result, the speed of the particle—and thus its kinetic energy—remains unchanged, leading to circular or helical motion.
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.
If a current passed in spring then?
remains unchanged
What isotope is produced when np 239 emits a beta particle?
When neptunium-239 (Np-239) emits a beta particle, it undergoes beta decay, which transforms a neutron into a proton. This process results in the formation of plutonium-239 (Pu-239), as the atomic number increases by one while the mass number remains the same. Thus, the isotope produced is plutonium-239.
Which type of radioavtive decay does the mass number remain unchanged?
In gamma decay, the mass number remains unchanged as there is no emission of particles, only high-energy gamma rays are emitted. This process does not affect the nucleus composition, unlike alpha and beta decays which result in a change in the mass number.
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.
If you move an object from the base of a mountain to the top of the mountain what remains unchanged?
The mass of the object remains unchanged, as it depends only on the amount of matter in the object.
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.
