When an atom undergoes radioactive decay when does it become a completely different element?
An atom of a given isotope will undergo radioactive decay whenever it feels like it. No joke. The nucleus of a radioactive isotope is unstable. Always. But that atom has no predictable moment of instability leading immediately to the decay event. We use something called a half life to estimate how long it will take for half a given quantity of an isotope to undergo radioactive decay until half the original amount is left, but this is a statistically calculated period. No one knows how long it will take a given atom of a radioactive isotope to decay, except that those with very short half lives will pretty much disappear relatively quickly.
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
What are the various differences between a stable and an unstable nuclei?
The nuclei of a stable radioactive isotope will after been bombarded with a neutron produce a radiation and enormous energy and such reaction will come to an end, while the nuclei of an unstable nuclei will continue to react with little fragment of the neutron continuously (long chain nuclear reaction) until it has attain it stable phase.mind you this reaction with the little fragment of this neutron can last over 10 years.
Can a radioactive object make another object radioactive when it touches it?
Mostly no, but it depends on the nature of the two objects. Radioactive objects are usually emitters of alpha particles (helium nuclei), beta particles (electrons), and/or gamma rays (high-energy photons). None of those will usually induce secondary radioactivity in other objects. However, if neutrons are emitted, they can often penetrate the nuclei in another object, and if successfully absorbed there, can produce an unstable (radioactive) isotope. Also, if the source radioactive object is producing radon gas as a decay product, that can also be absorbed by some materials and start generating radiation there. (This does not require that it be "touching".)
As radioactive uranium decay it turns into what stable element?
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 property of a radioactive isotope is the length of time it takes half of the nuclei to decay?
This is called the "half-life" of the isotope.
Process which unstable nuclei emit radiation is called?
This process through which unstable nuclei emit radiation is called radioactive decay. It also is called nuclear decay, and it is a natural process in which an atom of an isotope decomposes into a new element.
What word means unstable elements that decay?
The word Radioactive usually denotes a substance containing unstable atomic nuclei.
What is an electron emitted from an atom into two nuclei with smaller masses is?
its called an isotope c:
What is the length of time it takes for one half of the nuclei of a radioactive isotope to decay?
It can vary from tiny fractions of a second to several sextillion years.
The splitting of nuclei of atoms is called .?
The splitting of nuclei of atoms is called nuclear fission. This process is categorized as either a nuclear reaction or a radioactive decay reaction.
What is the required for half a sample of radioactive nuclei to decay called?
not sure you're asking exactly but I think the answer your looking for is radioactive half-life
Does radioactive isotopes have a stable nuclei?
Radioactive isotopes are not stable.

Radioactive substances consist of nuclei that can't be held together by the what?
Radioactive substances consist of nuclei that can't be held together by the strong force.
All radioactive nuclides of an element have the same half life?
No, halflife is a bulk statistical property of a quantity of an isotope of an element.Individual nuclei do not have halflives, instead they have a probability of decaying at the current moment of time.
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
