Depending on the specific element and isotope it can release neutrons, alpha particles (Helium-4 nuclei), beta particles (electrons and positrons), and gamma radiation (energy in the form of electromagnetic radiation)
Because they are both in the nucleus and if they weren't the element would be radioactive.
It would become a different element. It could become radioactive.
By definition. If it were stable, then it would not be radioactive.
The element with mass number 260 does not exist naturally. However, an artificial element with the mass number 260 could be produced in a nuclear reaction involving a heavy nucleus and would likely be a radioactive isotope.
It would be radioactive and the nucleus would undergo nuclear decomposition.
If you are referring to a cell's nucleus than the simple answer is that's not radioactive. Radioactivity occurs when elemental atoms become unstable due to the loss or gain of additional neutrons; these unstable atoms are referred to as radioactive isotopes. If a cell's nucleus were radioactive it would not last very long, its structure and function would quickly degrade and collapse.
Usually, uranium, specifically, uranium-235.
NO!!! Because if it was, there would not be any silver jewellery/cutlery etc., about, because the radio-activity woulkd be dangerous.
Assuming that two neutrons and two electrons are also added, the atomic number would shift from 80 to 82, resulting in lead. If the neutrons or electrons were not added, it would be the radioactive isotope, lead-206.
That would be radioactive decay.
If 4 neutrons were added to the nucleus of an original element, it would become an isotope of that element. Isotopes have the same number of protons (and thus the same atomic number) but differ in their mass due to the additional neutrons. This change can affect the stability of the nucleus, potentially making it radioactive if the neutron-to-proton ratio becomes unfavorable. The chemical properties of the element would remain largely unchanged since they are primarily determined by the number of protons.
Element Am is Americium. Americium is radioactive element number ninety five. I would not wanna mess with Americium
