A1 My best answer is some. some isotopes may be but i don't completely know.
answ2. Most man made nuclides have short half lives. I haven't counted them on a chart, but I'd guess at least ten times the number of man made to natural.
Of course, soon after the Super Nova; from the debris of which the Solar System was assembled; a number of these nuclides would be present, having been created in the Nova. But they would have had the same short half lives.
[Oh yes, all your atoms were once part of a star!]
What else can I help you with?
Is chromium radio active?
Natural chromium is not radioactive. However, there are radioactive isotopes of chromium, such as chromium-51, that are man-made through nuclear reactions. These radioactive isotopes are used in various medical and scientific applications.
Why is silver radioactive?
Silver itself is not radioactive. However, certain isotopes of silver can be radioactive. For example, silver-108 and silver-110 are radioactive isotopes with long half-lives that can undergo radioactive decay. These isotopes are not commonly found in nature.
Is xenon radioactive?
None of the isotopes of xenon ordinarily found in nature is radioactive. Like all elements, xenon has synthetic radioactive isotopes.
Are most isotopes stable?
No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
Number of isotopes in lithium?
Lithium has two stable isotopes, lithium-6 and lithium-7. There are also several radioactive isotopes of lithium, with lithium-8 being the most common radioactive isotope.
Is chromium radio active?
Natural chromium is not radioactive. However, there are radioactive isotopes of chromium, such as chromium-51, that are man-made through nuclear reactions. These radioactive isotopes are used in various medical and scientific applications.
Does Barium have isotopes that are all radioactive?
No, Barium has both stable and radioactive isotopes. Out of its 25 known isotopes, only 6 of them are considered radioactive. The most stable isotope of Barium is Barium-138, which is not radioactive.
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
How are radioactive isotopes different from isotopes?
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Does sodium contain radioactive isotopes?
Sodium has no radioactive isotopes.
Does radioactive isotopes have a stable nuclei?
Radioactive isotopes are not stable.
Does plutonium have isotopes that are all radioactive?
All the uranium isotopes are radioactive.
What happens to all radioactive isotopes?
All radioactive isotopes will disintegrate.
Can isotopes be radioactive or non-radioactive?
No not all isotopes are radioactive, However there certainly are several elements which have no stable isotopes.these are the man made elements also known as "Not found in nature". such as:Tc - Technetium (43)Pm - Promethium (61)Np - Neptunium (93)Pu - Plutonium (94)Am - Americum (95)Cm - Curium (96)Bk - Berkelium (97)Cf - Californium (98)Es - Einsteinium (99)Fm - Fermium (100)No.No, not all isotopes are radioactive. Only atoms that are unstable (carbon-14, etc.) are radioactive
Are all isotopes of francium radioactive?
All isotopes of francium are radioactive.
Isotopes which have unstable nucleus and break down at a constant rate over time?
radioactive isotopes! :)
Is radioactivity man made?
Some isotopes of elements are naturally radioactive, meaning they emit radiation spontaneously. However, humans have also created radioactive isotopes through processes such as nuclear reactors and weapons testing. So while radioactivity can occur naturally, it can also be man-made.
