What is the daughter nucleus in the alpha decay of radon 222?
polonium-218 Radon-222 itself alpha decays to polonium-218 with a half-life of approximately 3.82 days, making it the most stable isotope of radon. Its final decay product is stable lead-206.
When a nuclide undergoes an alpha decay?
A nuclide A undergoes α decay and another nuclide B undergoes β−decay. All the α particles emitted by A will have almost the same speed. All the α particles emitted by A may have widely different speeds. All the β particles emitted by B will have almost the same speed.

43, we find it is technetium, Tc, 10343Tc .

Polonium-212 undergoes alpha decay to produce lead-208, which means that it gives off alpha radiation, i.e. alpha particles.
What is the product of the alpha decay of U 238?
thorium-234 Uranium-238 undergoes alpha decay to become thorium-234. (The numbers following the chemical names refer to the number of protons plus neutrons.) In this reaction, uranium-238 loses two protons and two neutrons to become the element thorium-234.
How do you find the daughter nuclide?
Alpha decay of the 238U "parent" nuclide, for example, produces 234Th as the "daughter" nuclide. The sum of the mass numbers of the products (234 + 4) is equal to the mass number of the parent nuclide (238), and the sum of the charges on the products (90 + 2) is equal to the charge on the parent nuclide.
What is the daughter product of radon-222?
222Rn, a daughter of 226Ra which emanates from the earth's crust and decays in the atmosphere, gives rise to a natural radioactive fallout of its daughters 210Pb, 210Bi, and 210Po (Burton and Stewart, 1960).
What is a parent and daughter nuclide?
A nuclide before disintegration is called a parent nuclide and that after disintegration is called a daughter nuclide. Some radionuclides remain energetically unstable even after disintegration, which means that the original radionuclides have transformed into other types of radionuclides.
What is the product of the decay of polonium 208?
Expelling two protons and two neutrons will reduce the mass number by four. This means the alpha decay of polonium-210, the most abundant isotope, will change the polonium atom to an atom of lead-206….Alpha Decay.
| Parent isotope | Daughter isotope |
|---|---|
| polonium-208 | lead-204 |
| polonium-210 | lead-206 |
| polonium-211 | lead-207 |
| polonium-212 | lead-208 |
What is the daughter product in the alpha decay?
alpha particle Alpha (α) Decay In the decay process, this excess mass is converted into energy and appears in the form of kinetic energy in the daughter nucleus and the alpha particle. Most of the kinetic energy is carried away by the alpha particle because it is much less massive than the daughter nucleus.
When uranium-238 decays What is the daughter product that is produced?
thorium 234 A nucleus of uranium 238 decays by alpha emission to form a daughter nucleus, thorium 234.
What is the daughter nuclide in A decay?
The phenomenon wherein a radionuclide emits radiation and transforms into a different nuclide is called disintegration. A nuclide before disintegration is called a parent nuclide and that after disintegration is called a daughter nuclide.
What is the daughter nucleus of this decay?
The original nucleus is called the parent nucleus, and the nucleus remaining after the decay is called the daughter nucleus. The process of one element changing into another through radioactivity is called transmutation.
What is the daughter product of radon?
Radon emits alpha particles and produces several solid radioactive products called radon daughters or "progeny". Some amounts of radon gas and radon progency are present everywhere in the soil, water, and air. Particularly high radon levels occur in regions where the soil or rock is rich in uranium.
What is radon a decay product of?
Radon (chemical symbol Rn) is an odorless, colorless, radioactive gas. It comes from the natural decay of uranium and radium found in nearly all rocks and soils. Radon can move up from the ground into buildings through openings in floors or walls that are in contact with the ground.
What is the daughter nuclide?
A nuclide before disintegration is called a parent nuclide and that after disintegration is called a daughter nuclide. A nuclide whose daughter nuclide is energetically unstable repeats disintegration until becoming energetically stable. Radioactive.
What happens when polonium undergoes alpha decay?
Alpha decay of polonium will always produce a lead isotope as the daughter isotope because the loss of two protons changes the atom's atomic number from 84 to 82. The mass number of the isotope also decreases by four because there are four nuclear particles in the ejected alpha particle.
What is the product of the alpha decay of U-238?
thorium-234 Uranium-238 undergoes alpha decay to become thorium-234. (The numbers following the chemical names refer to the number of protons plus neutrons.) In this reaction, uranium-238 loses two protons and two neutrons to become the element thorium-234.
What is the final product formed when uranium-238 undergoes radioactive decay?
The series of decay products created to reach this balance is called the decay chain. For example, the decay chain that begins with Uranium-238 culminates in Lead-206, after forming intermediates such as Uranium-234, Thorium-230, Radium-226, and Radon-222. Also called the "decay series.".
What is the daughter product?
Isotopes that are formed by the radioactive decay of some other isotope. In the case of radium-226, for example, there are 10 successive daughter products, ending in the stable isotope lead-206.
What does radon decay into?
Radon is a radioactive gas. Its decay products (polonium, bismuth and lead) are metals that can easily attach to dust and other particles in the air.
What does radon become when it decays?
Radon undergoes radioactive decay, when it releases ionizing radiation and forms “daughter” elements, known as decay products. It is the release of radiation from this decay process that leads to exposure and health risks from radon.
What is radon daughter?
Radon emits alpha particles and produces several solid radioactive products called radon daughters or "progeny". Some amounts of radon gas and radon progency are present everywhere in the soil, water, and air. Particularly high radon levels occur in regions where the soil or rock is rich in uranium.
What is the daughter nuclide in a decay?
The phenomenon wherein a radionuclide emits radiation and transforms into a different nuclide is called disintegration. A nuclide before disintegration is called a parent nuclide and that after disintegration is called a daughter nuclide.
What element is formed when polonium 214 undergoes alpha decay?
For example, polonium-214 with atomic number 84 and mass number 214 decays to lead-210 with atomic number 82 and mass number 210.
What happens during alpha decay?
Alpha decay is a nuclear decay process where an unstable nucleus changes to another element by shooting out a particle composed of two protons and two neutrons. This ejected particle is known as an alpha particle and is simply a helium nucleus.
What is the daughter nucleus of uranium-238?
thorium 234 A nucleus of uranium 238 decays by alpha emission to form a daughter nucleus, thorium 234. This thorium in turn transforms into protactinium 234, and then undergoes beta-negative decay to produce uranium 234.
What is a daughter nuclide?
A nuclide before disintegration is called a parent nuclide and that after disintegration is called a daughter nuclide. Some radionuclides remain energetically unstable even after disintegration, which means that the original radionuclides have transformed into other types of radionuclides.

Isotopes that are formed by the radioactive decay of some other isotope.
