plutonium-241
Explanation: 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 is the process by which the nucleus of an atom changes so that a new element is formed?
Nuclear transmutation is the process by which the nucleus of an atom changes, resulting in the formation of a new element. This can occur through radioactive decay, nuclear fission, or nuclear fusion, where the number of protons in the nucleus changes, leading to the creation of a different element.
What atom undergoes radioactive decay what is actually split or affected the most?
nucleus
What body organ is most likely harmed by explosure to radioactive iodine?
The thyroid gland is most likely harmed by exposure to radioactive iodine. Radioactive iodine can be absorbed by the thyroid gland, leading to an increased risk of developing thyroid cancer or other thyroid disorders.
Radioactive decay can be affected by what?
Most types of radioactive decay cannot be affected by anything. However, radioactive decay involving electron capture will be affected by the removal of electrons from around the nucleus. In the absence of orbital electrons, it cannot occur at all.
Which of the foods below wouldbe consideredthe most nutrient dense?
pizza, submarine sandwich
Where is the electron most likely to be found in the nucleus of an atom?
The electron is most likely to be found in the electron cloud surrounding the nucleus of an atom, rather than inside the nucleus. The nucleus contains protons and neutrons, while electrons are located in the electron orbitals outside the nucleus.
Which pathways is most likely taken by newly synthesized histones?
cytoplasm -> nucleus
When looking at eukarytoic cell under a light microscope what is most easily seen?
most likely the nucleus
What radioactive element is in nuclear reactions?
Uranium is one of the most common radioactive elements used in nuclear reactions. It undergoes nuclear fission, where its nucleus is split into smaller fragments, releasing energy in the process.
Can 250000 tons of radioactive waste a year kill you?
it would most likely kill you the first time
Does the nucleus contain electrons?
Yes; the 1s electrons are most likely to be in the nucleus.No, the electrons are on the outer shell, but a nucleus contains neutrons and protons.
Each of the objects below has a different amounts remaining of the original radioactive material X. Which object is most likely the oldest?
The object with the smallest amount of original radioactive material X remaining is most likely the oldest. Over time, radioactive material decays at a consistent rate, so the object with the least remaining material has been decaying the longest.
