When one neptunium isotope undergoes an alpha decay what does it become?
Npn decays to Pan-4 and alpha. Only isotopes 234, 235, and 237 of neptunium can undergo alpha decay, the others decay by beta-, beta+, K capture, and/or gamma decay. So the only products of neptunium alpha decay can be protactinium isotopes 230, 231, or 233.
What type of radiation is emitted when polonium forms lead-208?
Lead-208 is formed by alpha decay (emission of alpha particles) from polonium-212.
How does americium - 241 undergo beta decay?
Americium-241 has an alpha decay associated with gamma.
When an isotope is what it does not undergo radioactive decay?
friends are like seashells you collect on the way
What is the alpha decay of plutonium 239?
The daughter isotope of Pu-239 is U-235.
What is the decay process that polonium undergoes?
All isotopes of polonium can undergo alpha decay, a small number of isotopes can also undergo beta decay, K capture decay, or gamma decay.
What is the balanced reaction for the predominant method of decay of radon?
In the case of Rn-222, which is the "isotope of concern" because it occurs naturally, it decays as follows: 222Rn => 218Po + He+2 In this equation, we see the radon isotope Rn-222 emit an alpha particle (the helium nucleus) and undergo a transformation to become the polonium isotope, Po-218.
What isolope remains after the alpha decay of polonium -212?
After the alpha decay of polonium-212, the remaining isotope is lead-208. The alpha decay involves the loss of an alpha particle, which is a helium-4 nucleus consisting of two protons and two neutrons. This causes the atomic number to decrease by 2 and the mass number to decrease by 4, resulting in lead-208.
What isotope remains after the alpha decay of polonium 212?
Polonium 212 has 84 protons and 128 neutrons. An alpha particle is 2 protons and 2 neutrons, so the daughter nucleus will have 82 protons and 126 neutrons, making it lead 208.
What pathway would decay polonium-218 to bismuth-214?
Polonium-218 undergoes alpha decay to form lead-214, which then undergoes beta decay to form bismuth-214.
What is the symbol for Alpha Radiation?
The isotope radon-198 will alpha decay to polonium-194 as shown here: 86198Rn => 24He + 84194Po The radon is shown on the left, and the alpha particle, which is a helium nucleus, is shown of the right with the polonium.
What does the symbol PO-210 represent?
The symbol Po-210 represents the radioactive isotope of polonium with an atomic number of 84 and a mass number of 210. Polonium-210 is a highly toxic substance that emits alpha particles during radioactive decay.
Which equation correctly represents the alpha decay of polonium 214?
The correct equation for the alpha decay of Polonium-214 is: 218/84Po -> 214/82Pb + 4/2He This shows the decay of Polonium-214 into Lead-214 and a Helium nucleus, where the atomic number and mass numbers are conserved.
Which two elements undergo alpha decay?
The two elements that undergo alpha decay are uranium and thorium.
How many isotopes of polonium are part of the decay?
Each isotope has a specific radioactive decay.
What daughter product remains after the alpha decay of polonium-212?
The daughter product that remains after the alpha decay of polonium-212 is lead-208. During alpha decay, polonium-212 loses an alpha particle, consisting of two protons and two neutrons, resulting in the transformation to lead-208.
When an isotope is blank it does not undergo radioactive decay?
When an isotope is stable, it does not undergo radioactive decay. Stable isotopes have a balanced number of protons and neutrons in the nucleus, which prevents them from spontaneously changing into another element over time.
