Uranium-239 decays by beta- decay to neptunium-239.
The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element. The atom that decayed is called the parent.
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).
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.
There is no element carbon-40. The highest known isotope of carbon is carbon-23. Please restate the question.
Radioactive decay happens in an unstable isotope of a given element, as the isotope decays radiation is given off. As for when exactly, the decay of a nucleus is spontaneous and random so averages are used, these averages are different for different isotopes, but are measured as the "half life" (the time it takes for half the nucleus to decay).
This isotope is transformed in another isotope of another element.
radioactive decay
These terms apply to the decay of radionuclides. The parent isotope is 'the starting point' of a decay series that when it decays, by giving off radiation, changes into another element, or isotope of the original element (the daughter isotope). For example: When Uranium 238 (parent isotope) decays and gives off an alpha particle, it transmutes into Thorium 234 (the daughter isotope).
A radioactive element (atom) can decay up to a stable isotope.
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
During nuclear decay, radioisotopes of one element can change into one or more isotopes of a different element altogether.
This isotope is radium-226.
For the most common isotope of neptunium, Np-237, the decay daughter is protactinium-233.Each isotope has another type of decay.
Neptunium-237 decay to protactinium-233.Each other isotope has another schema of decay.
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element. The atom that decayed is called the parent.
