What conditions in the nucleus are likely to result in an atom undergoing radioactive decay?

A nucleus can be inherently unstable. It can absorb an energetic photon (photoactivation) and become unstable. It can capture positrons, electrons, neutrons, and protons and become unstable. Decay processes include: # Alpha emission, a high energy 4He nucleus # Beta emission, a high energy electron # Beta+ emission / Beta capture, either a positron is emitted or an electron is captured into the nucleus (Burp!) # Gamma emission, one or more high energy photons are emitted # Neutron emission, neutrons of varying energies may be ejected in the process of a heavy nucleus decay (even tritium).

∙ 11y ago- alpha, 2 protons & 2 neutrons leave the nucleus
- beta, neutron changes to proton in nucleus
- antibeta, proton changes to neutron in nucleus
- capture, proton captures electron and changes to neutron in nucleus
- gamma, excited energy state of nucleus relaxes

Why are rocks hot?
If a rock is hot, it has been heated by a source of heat, either man-made or natural. However the rock itself, may be the source of heat - in which case it contains radioactive material undergoing decay and is most likely dangerous!
What happens if an atom is too ionized?
If your atom is too ionized, it will likely zip away from you and attach itself to a nearby atom or molecule. An atom becomes radioactive when its nucleus contains too many or too few neutrons. Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great, radioactive decay will occur.
Which of the following nuclei is likely to release energy when undergoing nuclear fusion?
3 H (deuterium) 1
What isotope uranium is radioactive?
Yes.......most likely. I can't think of anything to do with Uranium, that isn't radioactive! -------- Uranium natural isotopes are not so radioactive compared with other isotopes; but all the isotopes of uranium are radioactive.
Is likely to exit a cell via exocytosis?
nucleus
Which atoms are least likely to be radioactive?
Generally, the smaller the nucleus, the less radioactive.
What is likely to happen to atoms like plutonium with many neutrons and a heavy nucleus?
Radioactive disintegration or spontaneous fission
What is the process by which the nucleus of an atom changes so that a new element is formed?
Most likely this is some sort of radioactive decay.
Which nucleus would-be MOST likely to be radioactive?
plutonium-241Explanation: Pu-241 is a highly radioactive isotope. It is used in nuclear reactors and nuclear bombs because of its instability. The others have a ratio of one proton to one neutron and are very stable.There are some elements that have no stable nucleus. Most notably Technetium and most elements above Lead.
What elements are radioactive?
Answerelements with a nonstable isotope or at least one naturally occurring isotope that is radioactive. AnswerAll elements have radioactive isotopes.There are a lot of radioactive elements: Technetium, Promethium, Polonium, Astatine, Radon, Francium...Here is the whole list: http://periodictable.com/Elements/Radioactive

What makes a chemical radioactive?
An element is radioactive if its atomic nuclei are unstable. The nucleus contains protons and neutrons; the electromagnetic force pushes the protons apart because they have the same charge, but the strong nuclear force pulls the protons and neutrons together. A nucleus is only stable if it has the right balance of protons and neutrons, and doesn't have any extra energy (if it does, it is said to be in an excited state).An unstable nucleus will sooner or later change its state by undergoing radioactive decay. There are many kinds of radioactive decay, but four are particularly well known:* The nucleus may eject a cluster of two protons and two neutrons, which is called an alpha particle.* A neutron may convert into a proton by emitting an electron (in this context called a beta particle) and an antineutrino.* An excited nucleus may release energy in the form of a photon, called a gamma ray.* The nucleus may break up into two or more smaller nuclei, typically releasing one or more neutrons in the process; this is called spontaneous fission.
