What is nuclear isotopes?
A radioactive isotope is a form of an element that is unstable and eventually decays into a different element. For example, most Carbon has 6 protons and 6 neutrons, and is stable. This is called Carbon12.Carbon14 with 6 protons and 8 neutrons, is unstable and decays by releasing a beta particle from its nucleus to become a stable isotope, Nitrogen14. which has 7 protons and 7 neutrons.That refers to an isotope that is unstable - the atoms will decay after a while.
How is uranium transfered into energy?
the uranium isotope 335 is the "uranium" you are thinking of. uranium 335 is bombarded with one neutron. this turns it into uranium 336 which is extremely unstable. the isotope splits into krypton and barium, and three neutrons. but two neutrons are converted into energy.
What is it meant by the term stable isotope?
Stable isotopes do not undergo nuclear decay. Hydrogen has three isotopes, two are stable and the third is unstable. They are ;_ protium; 1 proton , 0 neutrons and 1 electron (Stable) The commonest isotope of hydrogen. deuterium ; 1 proton , 1 neutron and 1 electron (stable). Also known as 'heavy hydrogen - used to make heavy water). tritium ; 1 proton , 2 neutrons, and 1 electron (unstable - undergoes radio-active decay).
What is shot at an isotope's nucleus to trigger a nuclear chain reaction?
neutrons
What determines the nuclear stability of an isotope?
To be an isotope stable, the number of neutrons should not exceed 1.5 times than protons.

Nuclear decay is the change of an atom of...?
... an unstable isotope to a more stable isotope by emission of some type of radiation (alpha, beta, or gamma).
What is nuclear instability?
Nuclear instability is when the nucleus of an atom is unstable because of an improper ratio of protons to neutrons. Nuclear instability causes radioactive decay because the nucleus emits radiation to stabilize itself.
What makes a nucleus unstable?
The strong nuclear force doesn't balance the electrostatic force.

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.
Describe the nature of the emitted particles in Uranium?
Uranium, for example the isotope 235 is an emitter of: gamma, alpha and beta radiations, also spontaneous fission neutrons. But, for each isotope of uranium the radiation energies, and their percentage is different.

neutrons
Does nuclear radiation go away?
No, it doesn't.Wrong, it does. There are 2 types of nuclear radiation: prompt & decay.Prompt nuclear radiation occurs for a period of time while the reaction that generates it is happening. Examples are the flash of neutrons, light, x-rays, etc. when a nuclear bomb explodes as well as the sustained neutron flux as a nuclear reactor is in operation. When the reaction stops, prompt nuclear radiation goes away.Decay nuclear radiation occurs as radioactive isotopes decay to different isotopes. As the decay happens (which is a probabilistic process) the radioactive isotope is consumed. This follows an exponential function with one half of the current amount of the radioactive isotope consumed in each period of time called a halflife. While there will always be a tiny residue of the original radioactive isotope, for practical purposes it is considered to be negligible after 5 halflives have passed. When 5 halflives of the radioactive isotope decaying have passed, decay nuclear radiation is considered to have gone away for practical purposes.
What is the definition for radioactivity?
Spontaneous emission of ionizing radiation as a consequence of a nuclear reaction, or directly from the breakdown of an unstable nucleus; The radiation so emitted; including gamma rays, alpha particles, neutrons, electrons, positrons, etc
What are some forms of nuclear radiation?
Nuclear radiations include:Alpha radiationBeta radiationGamma radiation or x-raysFast or slow neutrons
