No. The sun is made up of a ball of gases, and the only radioactive gas we know of is Radon. Also, most radioactive elements are man-made.
yes
As the simulation proceeds, the number of radioactive atoms decreases due to their decay into daughter atoms. Conversely, the number of daughter atoms increases as more radioactive atoms decay over time. This process continues until a stable ratio is reached, where the decay of parent atoms and the formation of daughter atoms balance out. Eventually, the count of radioactive atoms will approach zero while the number of daughter atoms may stabilize at a constant level.
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
The half-life
Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
yes
The numbers of radioactive and daughter atoms may or may not change at the same rate throughout simulation when compared to each other. Atoms generally start out at a higher rate of speed, and decrease to a lower one.
Yes, the percentage of radioactive atoms that decay during one half-life is always the same, which is 50%. This means that half of the radioactive atoms present will undergo radioactive decay within each half-life duration.
A. Different atoms of the same nuclide have different half-lives.B. each radioactive nuclide has its own half-life.C. All radioactive nuclides of an element have the same half-life.D. All radioactive nuclides have the same half-life.
All atoms are nuclear, in that they all have nuclei. Some atoms have unstable nuclei, making them radioactive. I'm afraid I have no idea what you mean by "nuclear atoms," unless you meant to say radioactive atoms, in which case the answer is "they have unstable nuclei and they're radioactive."
No
Not always. Some atoms of the same element with different numbers of neutrons are radioactive, whereas the other atoms are not.
They are al in space, and made of the same materials and atoms.
Yes. All of the actinides are radioactive.
No, the Sun does not produce energy through radioactivity. The Sun's energy comes from nuclear fusion reactions in its core, where hydrogen atoms are fused into helium, releasing vast amounts of light and heat in the process.
The half-life of a radioactive element is the time it takes for half of the atoms in a sample to decay. As the sample decays, the number of radioactive atoms decreases while the number of stable atoms increases. The process continues in this manner, with each half-life reducing the amount of radioactive material by half.
As the simulation proceeds, the number of radioactive atoms decreases due to their decay into daughter atoms. Conversely, the number of daughter atoms increases as more radioactive atoms decay over time.
