A = mass number = sum of p+ and n0
Z = atomic number = no. of p+
An alpha particle consists of two protons and two neutrons, so if an one were to be emitted from a radioactive atom, the atomic number (Z) would be reduced by two, and the mass number (A) would be reduced by four.

When uranium-238 atomic number 92 decays by emitting an alpha particle it becomes?
When uranium-238 (atomic number 92) decays by emitting an alpha particle, it transforms into thorium-234 (atomic number 90) because an alpha particle contains two protons and two neutrons, reducing the atomic number by two.
What happens to the atomic number of an element if it emits 1 alpha particle and 3 beta particles?
It depends on whether the beta decay is beta- or beta+. The alpha emission reduces the atomic number by 2. Beta- increases the atomic number by 1 while beta+ decreases the atomic number by 1. You do the math.
How does gamma emission differ from all the other types of decay?
Gamma emission is a type of decay in which a nucleus releases high-energy gamma photons without changing its atomic number or mass number. This is different from alpha and beta decay, which involve the emission of particles from the nucleus. Gamma emission is a form of electromagnetic radiation, while alpha and beta decays involve the emission of particles with mass.
What happen to atomic number and mass number of nucleus when it emits alpha particle electron and proton?
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
When an alpha particle is emitted the atomic increases by what?
The emission of an alpha particle (which is a Helium nucleus) from a radioactive nuclide would decrease its atomic number (z) by two, and its mass number by 4. So for example, Plutonium-239 (z=94) would emit the alpha particle and jump back down the table to Uranium-235 (z=92). It is possible to go up the table (increase atomic number) through certain beta decays.
What is the effect on the mass number and change of a nucleus when it loses alpha particles?
The mass number goes down by 4, and the atomic number goes down by 2 when a nucleus loses an alpha particle. XYZ --> alpha emission --> X-2Y-4Q + 24He2+
What happens to a radioisotope when it undergoes alpha emission?
During alpha emission, a radioisotope emits an alpha particle, which is composed of two protons and two neutrons. This reduces the atomic number of the parent isotope by 2 and the atomic mass by 4. The emission of an alpha particle transforms the parent isotope into a new element.
If the isotope bismuth-213 emits an alpha particle two protons and two neutrons which element will be left over?
Lead-209 will be left over after the isotope bismuth-213 undergoes alpha decay, as the emission of an alpha particle causes the atomic number of the element to decrease by 2. Bismuth-213 has an atomic number of 83, so after the emission of an alpha particle (which has an atomic number of 2), the resulting element will have an atomic number of 81, which corresponds to lead.
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.
What is The alpha emission process results in the daughter nucleus differing in what manner from the parent?
Atomic number increases by one.
How does radon-222 decay by alpha emission?
Radon-222 decays by alpha emission through the release of a helium nucleus, which consists of two protons and two neutrons. This process reduces the atomic number of the radon atom by 2 and the atomic mass by 4.
What happens to the atomic number when an alpha particle is given off?
Alpha emission in an atom reduces its atomic number by two. A link can be found below to the related question about what alpha decay is.
When uranium-238 atomic number 92 decays by emitting an alpha particle it becomes?
When uranium-238 (atomic number 92) decays by emitting an alpha particle, it transforms into thorium-234 (atomic number 90) because an alpha particle contains two protons and two neutrons, reducing the atomic number by two.
What type of nuclear decay results in the atomic number decreasing by two and the mass decreasing by two?
Emission of an alpha particle.
What is the name of the elements that have the atomic number over 95?
All these elements are raidoactive, and will decay with the emission of alpha, beata or gamma radiation.
What happens to the atomic number of an element if it emits 1 alpha particle and 3 beta particles?
It depends on whether the beta decay is beta- or beta+. The alpha emission reduces the atomic number by 2. Beta- increases the atomic number by 1 while beta+ decreases the atomic number by 1. You do the math.
Daughter product in part a decays by alpha emission?
Alpha decay is the emission of an alpha particle, which consists of two protons and two neutrons. During alpha decay, the parent nucleus loses an alpha particle to become a different nucleus called the daughter product. The daughter product formed after alpha decay will have an atomic number that is two less and a mass number that is four less than the parent nucleus.
