What nuclear decay have no mass and no charge?
Gamma decay involves the emission of a gamma ray, which is a high-energy photon with no charge and no mass.
Why does gamma decay occur?
Gamma decay occurs when an excited nucleus releases energy in the form of a gamma ray photon in order to reach a more stable energy state. This type of decay often follows alpha or beta decay processes, as the nucleus transitions to lower energy levels. Gamma decay allows the nucleus to shed excess energy without changing its atomic number or mass.
A emission results in the release of energy without any apparent change in mass or nuclear charge.?
This process is known as gamma decay, which involves the emission of a gamma ray photon. Gamma rays are a form of electromagnetic radiation that carries energy but does not change the mass or nuclear charge of the atom. Gamma decay is typically associated with nuclear reactions and can occur after alpha or beta decay to stabilize the nucleus.
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 type of radioactive decay involves only the release of high energy photons and therefore does not change the mass of the radionuclide?
There is no normal process by which a nucleus can release energy without changing the element. Even gamma radiation, which is photon emission from the nucleus during a restabilization sequence, has a predecessor, i.e. usually beta or alpha, which does change the element.
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.
How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
When an unstable magnesium nucleus undergoes gamma decay, it remains as a magnesium nucleus. Gamma decay does not change the atomic number or mass number of the nucleus, only releasing a gamma photon to reduce excess energy.
Why does gamma decay result in no mass loss for the atom?
A gamma decay is simply emission of a photon. Technically, there must be a tiny mass loss of E/c2 . Decay is not reallya goodword because there is no loss of electrons, neutrons or protons so the nucleus is unchanged in its make-up. There is of course energy decay.
Does the nucleus mass or atomic number change during gamma ray decay?
The emission of a gamma ray changes neither the mass number nor the atomic number of a nucleus. An example of an equation for gamma emission is: 99mTc --> 99Tc + gamma The "m" associated with the mass number indicates a metastable nuclear isomer.
Is it possible for gamma decay to produce a new element?
no, gamma isn't really decay as the radioactive ion doesn't emit any particles. In alpha and beta decay, different size particles are emitted as the nucleus decays but in gamma radiatio the ion gives off an ionising electromagnetic wave.
What are the different types of radioactive decay and how do they differ from each other?
There are three main types of radioactive decay: alpha decay, beta decay, and gamma decay. Alpha decay involves the emission of an alpha particle, which is a helium nucleus consisting of two protons and two neutrons. This type of decay reduces the atomic number of the nucleus by 2 and the mass number by 4. Beta decay involves the emission of a beta particle, which can be either an electron (beta-minus decay) or a positron (beta-plus decay). Beta decay changes the atomic number of the nucleus by 1 but does not significantly affect the mass number. Gamma decay involves the emission of gamma rays, which are high-energy photons. Gamma decay does not change the atomic number or mass number of the nucleus but helps the nucleus reach a more stable energy state. These types of decay differ in the particles emitted and the changes they cause to the nucleus.
