What is produced when polonium-218 undergoes alpha decay?
An atom of polonium-218 undergoes alpha decay. What new element is produced? | Socratic An atom of polonium-218 undergoes alpha decay. What new element is produced? Lead. Alpha decay is the loss of two protons and two neutrons from a nucleus.
What is the product element of alpha decay?
Alpha decay is the loss of two protons and two neutrons from a nucleus. This decreases the total mass number by 4 and the atomic number by 2. Looking at the periodic table we can find that element number 82 is lead, Pb, so the product element X is Pb.
Which element has an atomic number equal to after alpha decay?
When a radioactive nuclide undergoes alpha decay, it emits an alpha particle, 4 2α, which is essentially the nucleus of a helium-4 atom. This means that after the alpha particle is emitted A quick look in the Periodic Table of Elements will show that the element that has the atomic number equal to
What is the equation for alpha decay?
Equation for Alpha Decay 1 is the parent nucleus 2 A is the total no.of nucleons 3 Z is the total no.of protons 4 is the daughter nucleus 5 is the released alpha particle
What particle is produced when Po 218 undergoes alpha decay?
When polonium - 218 decays, it emits a beta particle followed by an alpha particle.
What kind of decay is polonium 218 undergoing?
An atom of polonium-218 undergoes alpha decay.
What is the decay equation for polonium 218?
Answer and Explanation: The nuclear reaction is: 21884Po→21482Pb+42α 84 218 P o → 82 214 P b + 2 4 α .
What is the alpha decay of Po?
206PbPo is an alpha emitter that has a half-life of 138.376 days; it decays directly to stable 206Pb. The majority of the time, 210Po decays by emission of an alpha particle only, not by emission of an alpha particle and a gamma ray; about one in 100,000 decays results in the emission of a gamma ray.

What isotope remains after the alpha decay of polonium-212?
Polonium-212 undergoes alpha decay to produce lead-208, which means that it gives off alpha radiation, i.e. alpha particles.
What does the 218 mean in polonium 218?
Polonium-218 atom is the radioactive isotope of polonium with relative atomic mass 218.008966 and half-life of 3.10 min.
How many protons does polonium 218 have?
Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure.
What element is formed by alpha decay?
1. Alpha decay. An example of this decay occurs in the uranium-238 nucleus that decays into thorium-234 nucleus.
What's the alpha decay of polonium-210?
lead-206Thus 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 causes an atom of Polonium-211 to decay?
When an alpha particle is kicked out, the atom's mass is reduced by four, and its atomic number is reduced by 2. This means that it becomes a different element. Example: Polonium-211 is a very unstable isotope of polonium that will undergo alpha decay very quickly.
What happens when polonium-210 decays?
Po-210 decays to stable lead-206 by emitting alpha particles, accompanied by very low intensity gamma rays. The majority of the time Po-210 decays by emission of alpha particles only, not by emission of an alpha particle and a gamma ray. Only about one in a 100,000 decays results in the emission of a gamma ray.
What happens to polonium-218?
An atom of polonium-218 undergoes alpha decay.
What is the alpha decay of radon?
The decay of radon into polonium 218 is followed by further alpha decay into lead 214. Lead 214 emits then beta electrons to transform into bismuth 214 and polonium 214, which produces lead 210 through the emission of a third alpha particle.
What atom will be formed when polonium undergoes alpha decay?
Likewise, what atom will be formed when polonium undergoes alpha decay? Explanation: When a radioactive nuclide undergoes alpha decay, it emits an alpha particle, 42α , which is essentially the nucleus of a helium-4 atom.
What is the alpha decay?
Alpha decay can be described like this: The nucleus of these nuclei (parent nucleus) rich atoms splits into two parts. The alpha particle goes zooming off into space. The nucleus left behind (daughter nucleus) has its atomic number reduced by 2 and its mass number reduced by 4.
How many neutrons does alpha decay have?
This richness makes alpha decay possible. Thus, emitting its two protons and two neutrons in the form of an alpha particle and a forming of new daughter nucleus and attains a very stable configuration. Alpha decay can be described like this: The nucleus of these nuclei (parent nucleus) rich atoms splits into two parts.
What is the name of the particle that is produced by the nucleus during alpha decay?
In alpha decay, the nucleus emits an alpha particle or a helium nucleus. Alpha decay occurs in massive nuclei that have a large proton to neutron ratio. Alpha radiation minimizes the protons to neutrons ratio in the parent nucleus, thereby bringing it to a more stable configuration.
What type of decay is a particle with two neutrons and two protons ejected from the nu?
Alpha decay is a type of radioactive decay in which a particle with two neutrons and two protons is ejected from the nucleus of a radioactive atom.
What is the name of the decay in which the atoms are reduced by four?
Alpha decay or α-decay is a type of radioactive decay in which the atomic nucleus emits an alpha particle thereby transforming or decaying into a new atomic nucleus. Here the atomic mass number of the newly formed atom will be reduced by four and the atomic number will be reduced by two. The emitted alpha particle is also known as a helium nucleus.
How did Ernest Rutherford distinguish alpha decay from other forms of radiation?
Ernest Rutherford distinguished alpha decay from other forms of radiation by studying the deflection of the radiation through a magnetic field. The deflection of alpha decay would be a positive charge as the particles have a +2e charge.
Why are nuclei unstable?
They are called parent nucleus and they are basically unstable. Because the nuclei of these atoms have a lot more neutrons in their nuclei than protons, that is, they have too large a proton to neutron ratio, which makes these elements neutron-rich. This richness makes alpha decay possible.
