What is the most radioactive isotope known to date?
The most radioactive isotope known to date is Californium-252.
What is the stable isotope that is formed by the breakdown of a radioactive isotope?
The stable isotope formed by the breakdown of a radioactive isotope is called a daughter isotope. This process is known as radioactive decay, where a radioactive isotope transforms into a stable daughter isotope through the emission of particles or energy.
What is the atomic weight of plutonium?
Plutonium is a not stable, radioactive element. The IUPAC table Atomic weights of the elements, 2009 don't mention an officially atomic weight for plutonium. But you can find tables with atomic masses of the all 20 known plutonium isotopes (Audi, Wapstra, Thibault, 2003).The atomic mass of the most important isotope (239Pu) is 239,052156.
What is the characteristic time for the decay of a radioactive isotope?
The characteristic time for the decay of a radioactive isotope is known as its half-life. This is the time it takes for half of the radioactive atoms in a sample to decay.
Why is plutonium radioactive?
No it does not. There are various types (isotopes) of plutonium. Plutonium 238, the weapons grade material, has a half life of 88 years. Meaning after 88 years half of the material has transforms into another element through radioactive decay. Plutonium-240 has a half life of ~80 Million years. But eventually all types of plutonium will decay into other elements. All radioactive elements will eventually decay into non-radioactive atoms given enough time.
What is plutonium's atomic weight?
The atomic mass of the most important isotope of plutonium (239Pu) is239,052 156 34.The standard density of plutonium is 19,816 g/cm3at room temperature; but atomic mass of an isotope is not the density !
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
What is half of a radioactive isotope?
Half of a radioactive isotope is an atom that would have half of the atomic number of the radioactive isotope. In the case of radium-88 (88Ra), half of the radioactive isotope would be ruthenium-44 (44Ru). This assumes that the protons do not break down and that none are lost to additional reactions with other elements or compounds. Electrons can be lost along the radioactive chain, resulting in an ion of ruthenium rather than an electrically neutral atom.
What family is made up of all radioactive elements?
The family of radioactive elements is called the Actinides. This group includes elements such as uranium, thorium, and plutonium, which are known for their radioactive properties.
What is the symbol for the radioactive isotope known as Carbon 14?
The symbol for the radioactive isotope Carbon-14 is ^14C. The superscript 14 indicates the mass number of the isotope, which is the sum of protons and neutrons in the nucleus. The letter C represents the chemical element carbon.
Is Cesium a radioactive element?
Only one naturally occurring isotope of cesium is known, cesium-133 (133Cs) which is not radioactive. A number of artificial radioactive isotopes of cesium are known also. One radioactive isotope of cesium is of special importance, cesium-137. It is produced in nuclear fission reactions. Read more on cesium in the link below.
What is the half life of the radioactive isotope?
The half life is the period of time it takes radioactive decay to transmute one half of the isotope present at the start of the period to a different isotope, usually an isotope of a different element. This period of time is different for different isotopes, with known isotope half lives ranging from femtoseconds to many billions of years.
