What element does thorium-230 decay when it emits an alpha particle?
Thorium-230 decays into radium-226 when it emits an alpha particle.
Which radioisotope has an atom that emits a particle with a mass number of 0 and a charge of plus 1?
Proton emission is a type of radioactive decay where an atom emits a proton with a mass number of 0 and a charge of plus 1. An example of a radioisotope that undergoes proton emission is iodine-123.
What changes take place in the nucleus when an alpha particle is emitted?
When an alpha particle is emitted, there is a decrease of two protons and two neutrons in the nucleus, resulting in a new element with an atomic number reduced by two. This process is known as alpha decay, which helps to make the nucleus more stable.
What is radioisotope in a sentence?
A radioisotope is an unstable form of an element that emits radiation as it decays.
What radiation releases a helium particle?
Alpha radiation is essentially a Helium nucleus (not the whole atom, apha particles don't have electrons on them). An alpha particle is just two protons and two neutrons and as a result they also have a relative charge of +2.
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.
What element does californium make when it emits an alpha particle?
When californium emits an alpha particle, it creates curium.
What element does thorium-230 decay when it emits an alpha particle?
Thorium-230 decays into radium-226 when it emits an alpha particle.
What is the greatest amount of mass a radioisotopes emits?
The amount of mass a radioisotope emits is typically very small, on the order of atomic or subatomic particles such as alpha or beta particles. These emissions do not significantly affect the overall mass of the radioisotope.
What happens to a radioactive nucleus when it emits alpha particle and What happens to a radioactive nucleus when it emits alpha particle?
When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.
What change in mass occurs when a radioactive atom emits an alpha particle?
4 from the alpha. Betas have negligible mass and gammas have no mass.
What always occurs when a radioisotope emits radiation?
When a radioisotope emits radiation, it undergoes radioactive decay, transforming into a more stable element. This process releases energy in the form of radiation, which can be in the form of alpha particles, beta particles, or gamma rays.
If bismuth-213 emits an alpha particle what is it?
When bismuth-213 emits an alpha particle, it transforms into thallium-209. This process is known as alpha decay, where the atomic number decreases by 2 and the mass number decreases by 4 due to the emission of an alpha particle.
When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
What is the change in the atomic number when the atom emits an alpha particle?
The atomic number will decrease by 2, the number of protons in the emitted alpha particle. An alpha particle is a helium-4 nuclei with two protons and two neutrons.
What is lost from the nucleus of atom when it emits an alpha particle?
When an atom emits an alpha particle, it loses two protons and two neutrons from its nucleus. This results in a new element being formed with an atomic number that is two less than the original element.
What element does thorium become if it emits an alpha particle?
If thorium emits an alpha particle, it transforms into radium. This process is known as alpha decay, where the parent atom loses two protons and two neutrons to become a different element.
