Heavy radioactive elements (parent nuclei) decay to form daughter products that are as varied in number as the parents. Each heavy element has its own daughter.
To find the decay mode and end products of the radioactive decay for a given isotope, use a Table of Nuclides. A link is provided to the interactive chart posted by the National Nuclear Data Center at the Brookhaven National Laboratory.
The final stable element formed by all radioactive decay is lead (element number 82).
What else can I help you with?
Is u235 stable?
No, uranium-235 (U-235) is not stable. It is a radioactive isotope that undergoes radioactive decay, emitting particles and energy in the process.
All substances that naturally undergo radioactive decay do so until they finally become a stable isotope of one particular element what is the element?
The decay of radioactive substances follows a decay chain that will sooner or later result in the appearance of a stable isotope of lead. There is an exception for the atoms of a few substances that have undergone decay by spontaneous fission.
What does uranium become when it decays?
If we use uranium-238 as our starter isotope, what happens is that a nuclear decay event happens (in this case an alpha decay) and the U-238 transforms into a daughter isotope thorium (Th-234). The half-life of this transition is 4.5 billion years. Thorium-234 then undergoes a decay. And the process continues until a stable isotope is created as the last daughter of a decay chain. Note that there will be different half lives for the transition events, and the modes of decay will vary depending on what daughter is now the parent in the next decay event. Use the link below to see all the steps. The chart will show the whole chain including the half-life of isotope undergoing decay, the decay mode, and the daughter. Follow along using the keys and the process will reveal itself.
Does Argon Decay?
There are over twenty known isotopes of argon. Of these all but three are radioactive and decay. Of naturally occurring argon, very nearly 100% is not radioactive, with only traces of one radioactive isotope found.
What does it mean for an isotpe to be radioactive?
An isotope is radioactive if it undergoes spontaneous decay, emitting particles or radiation in the process. This decay results in the transformation of the atomic nucleus into a different element or a different isotope of the same element.
The uranium decay chain ends when the final disintergration product is the stable element?
Yes, that's correct. The uranium decay chain ends with the stable element lead-206. As uranium-238 undergoes alpha and beta decay, it transforms through various radioactive isotopes before reaching lead-206, which is stable and not subject to further radioactive decay.
Can a radioactive element completely decay so that it is all stable matter?
A radioactive element (atom) can decay up to a stable isotope.
What is the scientist Marie Curie known for?
discovery of the elements Radium and Poloniumstudying the decay chains from the radioactive element Uranium down to the stable element Lead
What radioactive element turns to lead when it has lost lots of energy?
It is uranium that is changed into lead during radioactive decay. Note that there are a number of intermediate steps in the conversion of uranium into stable lead. The uranium does not change directly into lead. The uranium atom undergoes decay, and a radioactive daughter product appears. This continues with radioactive daughters appearing at the end of every step - until lead appears.
Has Uranium changed over time?
The chemical and physical properties of uranium remain unchanged. But because uranium is a radioactive element the quantity of uranium on the earth is permanently changed due to radioactive decay.
What is the stable element for the uranium decay chain?
Isotopes of lead
What element is nonradioactive in the chain decay of uranium?
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
Can you get power from the radioactive element Uranium?
Yes, the radioactive decay of Uranium-235 is used to produce power in nuclear power plants.
Is u235 stable?
No, uranium-235 (U-235) is not stable. It is a radioactive isotope that undergoes radioactive decay, emitting particles and energy in the process.
What element is obtained through the decay of radium?
Radium naturally decays into radon, which is a radioactive noble gas. This decay process is one of the steps in the radioactive decay chain of uranium-238.
Which element is uranium transformed into?
The end element of the uranium decay chain is a stable isotope of lead.
What causes Uranium to be radioactive?
Uranium is radioactive because it is an unstable element with a nucleus that can undergo radioactive decay. During this decay process, uranium releases energy in the form of alpha, beta, or gamma radiation as it transforms into other elements over time. This radioactive decay is what makes uranium useful for nuclear energy and weapons.
