Is terbium radioactive?
Nearly all, 99.988%, of tantalum found in nature is stable. The natural radioactive isotope, 180mTa, accounts for 0.012% of it, and is believed to have a very long half life of about 1,200,000,000,000,000 years. Like all elements, tantalum has synthetic radioactive isotopes.
Is lutetium radioactive?
For most practical purposes, lutetium can be regarded as stable, though it is slightly radioactive. 97.41% of lutetium found in nature is stable, and 2.59% is of an isotope with a half life of 37,800,000,000 years. Like all other elements, lutetium has synthetic radioactive isotopes.
When does an unstable isotope break down into a stable isotope?
The process is called decay, or sometimes nuclear decay. A link can be found below.
What did Becquerel discovered from uranium?
He found that uranium is radioactive. Uranium is in the f block. Atomic number of it is 92.
What is Uranium's Natural State?
Uranium is a metal, solid and radioactive at room temperature.
Is the element Potassium stable or radioactive?
99.996% of calcium found in nature is not radioactive. 0.004% of natural calcium is radioactive 46Ca, and there are also trace quantities of radioactive 41Ca found naturally. Like all other elements, calcium has synthetic radioactive isotopes.The calcium you deal with in every day life is not, no. Some isotopes are, but they are not found in natural calcium deposits

A specimen is found to have 3 atoms of a radioactive isotope for every 9 atoms of the stable decay product The radioactive material has a half-life of 2500 years how old is the specimen?
5000 years old
What did Becquerel discovered from uranium?
He found that uranium is radioactive. Uranium is in the f block. Atomic number of it is 92.
Which element has the most electrons found natrully on earth?
I think uranium has the higgest number of electrons of all the naturally found elements. Uranium in its stable state have 92 protons and 92 electons but the thing that makes it radioactive is the number of neutrons (146). Purification of uranium from uranium oxide is really expensive.
Is uranium and radium produced from radioactive elements?
Uranium and radium, and a number of others, are natural elements found in the ground, and they are radioactive.
What is the use radioactive isotope in energy generation?
The most useful isotope is uranium 235 which occurs naturally as 0.7 percent uranium as found. Plutonium 239 is also useful but has to be made in a reactor from uranium 238
What isotope iodine iron phosphorus radium has the longest half-time?
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
What is the main use of Uranium-238?
The most common uranium isotope found in nature is Uranium-238. This particular isotope is mostly used in nuclear weapons and as the fuel supply for nuclear power.
What is Uranium's Natural State?
Uranium is a metal, solid and radioactive at room temperature.
