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.
When magnesium-28 undergoes beta decay what is the identity and the mass number of the nucleus formed?
When magnesium-28 undergoes beta decay, a neutron is converted into a proton, resulting in the formation of an aluminum-28 nucleus. The mass number remains the same at 28, as the total number of protons and neutrons is conserved during beta decay.
When the nuclide astatine-218 undergoes alpha decay?
When astatine-218 undergoes alpha decay, it emits a helium nucleus (alpha particle) and transforms into the new element, polonium-214. This process reduces the atomic number of the nucleus by 2 and the mass number by 4.
What nuclide is formed when 90Sr undergoes?
When 90Sr undergoes beta decay, it forms 90Y (Yttrium-90). In beta decay, a neutron is converted into a proton, and an electron (beta particle) and an antineutrino are emitted.
What is the beta decay of radium 226?
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
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.
When magnesium -28 undergoes beta decay what is the identity mass number of the nucleus formed?
aluminum-28
What atom undergoes radioactive decay what is actually split or affected the most?
nucleus
Which particle is emitted from a hydrogen-3 nucleus when it undergoes radioactive decay?
When a hydrogen-3 nucleus undergoes radioactive decay, it emits a beta particle (specifically an electron) and an anti-neutrino to transform into helium-3.
If Sulfur 34 undergoes alpha decay what will it become?
If Sulfur-34 undergoes alpha decay, it will become silicon-30. This is because in alpha decay, the parent nucleus loses an alpha particle (which is a helium nucleus composed of 2 protons and 2 neutrons), resulting in a new nucleus with an atomic number reduced by 2 and a mass number reduced by 4.
When magnesium-28 undergoes beta decay what is the identity and the mass number of the nucleus formed?
When magnesium-28 undergoes beta decay, a neutron is converted into a proton, resulting in the formation of an aluminum-28 nucleus. The mass number remains the same at 28, as the total number of protons and neutrons is conserved during beta decay.

When astatine-218 undergoes alpha decay, it emits a helium nucleus (alpha particle) and transforms into the new element, polonium-214. This process reduces the atomic number of the nucleus by 2 and the mass number by 4.
Beta decay of neodymium-144?
Neodymium-144 undergoes beta decay by emitting an electron (beta particle) and converting a neutron into a proton. This converts the neodymium-144 nucleus into the stable samarium-144 isotope. Beta decay is a type of radioactive decay that helps stabilize the nucleus by changing the neutron-to-proton ratio.
What is a nucleus that is unstable and undergoes decay?
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
Determine what type of decay occurs when thorium-231 undergoes radioactive decay to form protactinium-231?
Alpha decay occurs when thorium-231 undergoes radioactive decay to form protactinium-231. In alpha decay, a nucleus emits an alpha particle (two protons and two neutrons) to transform into a nucleus with a lower atomic number.
What is the process that allows the nucleus of Radium to become stable?
Nuclear decay.
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
