What is the daughter nucleus nuclide produced when po210 undergoes alpha decay?
Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82).
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 nuclear equation for the alpha decay of radon 222?
Radon-222 has an atomic number (Z) of 86 so an atom of radon-222 contains 86 protons in its nucleus. We now have a description of the particle lost as a nucleus that contains 4 nucleons, two of the nucleons are protons….Alpha Decay.

What is the daughter nucleus produced when sr83 undergoes positron emission?
so the daughter nucleus is Rubidium 83 and Atomic # 37.
What product nuclei are formed when 208 Po undergoes alpha decay?
Polonium-212 undergoes alpha decay to produce lead-208, which means that it gives off alpha radiation, i.e. alpha particles.
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 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 is the daughter nucleus of radon-222?
This element is called polonium, Po . The alpha decay of radon-222 will thus produce polonium-218, an isotope of polonium that has a mass number equal to 218 .
What is the product of the alpha decay of radon 220?
Answer: a) Po-216 See full answer below.
What is the daughter nucleus produced when kr79 undergoes positron emission replace each question mark with the appropriate integer or symbol?
Answer and Explanation: The daughter nucleus produced is Br-36. See full answer below.
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 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 are daughter nuclides?
Daughter Nuclide. daughter nuclide: a nuclide produced by the radioactive decay of another nuclide. May be stable or may decay further.
What is the formula for alpha decay?
The “Q-value” of the decay, Qα is the difference of the mass of the parent and the combined mass of the daughter and the α-particle, multiplied by c2. Qα = (mP − mD − mα)c2.
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 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 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 the daughter nucleus produced when kr79 undergoes positron emission daughter nucleus?
Answer and Explanation: The daughter nucleus produced is Br-36. See full answer below.
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 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 happens to the nucleus 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 emitted in alpha decay?
In alpha decay, a positively charged particle, identical to the nucleus of helium 4, is emitted spontaneously. This particle, also known as an alpha particle, consists of two protons and two neutrons. It was discovered and named by Sir Ernest Rutherford in 1899.
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.

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 are the products of radon decay?
Since radon is an unstable atom when it undergoes radioactive decay, it forms a number of short-lived radioactive decay products (called radon progeny), which include polonium (218Po), lead (214Pb), bismuth (214Bi), and polonium (214Po).
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.
When alpha decay occurs a nucleus emits an alpha particle and?
Alpha decay occurs when a nucleus is unstable because it has too many protons. The Figure below shows what happens during alpha decay. The nucleus emits an alpha particle and energy. An alpha particle consists of two protons and two neutrons, which is actually a helium nucleus.
