What is the shortest half-life of any known radioactive element?
The shortest half-life of any known radioactive element is that of francium-223, which is approximately 22 minutes.
Which radioisotope among the following has the shortest half-life?
The radioisotope with the shortest half-life among the following options is Polonium-214.
Which of the following color has the shortest wavelength?
Violet has the shortest wavelength while red has the longest.
What color of the spectrum has the second shortest wavelength?
According to (longest wavelength) ROYGBIV (shortest wavelength), it would be "indigo."
What type of EM radiation has the shortest wave length and the most energy?
Gamma rays have the shortest wavelength and the highest energy of all types of electromagnetic radiation. They are produced by radioactive decay and nuclear explosions.
Is samarium radioactive?
There are seven naturally occurring isotopes of samarium (Sm), and they are Sm-144 Sm-147, Sm-148, Sm-149, Sm-150, Sm-152 and Sm-154. Samarium's radionuclides Sm-147, Sm-148, and Sm-149 are alpha emiters. That is, they emit helium nuclei. The other isotopes are stable. A link can be found below.

What is the most radioactive substance in the world?
In general, those would be the substances that have the shortest half-life. There are lots of isotopes that decay in less than a second; in some cases, the half-life can be a millionth of a second, a billionth of a second, or even less. You can find some information about such isotopes in the Wikipedia article on "Nuclide".
What does directly or indirectly mean?
Directly means following a straight/shortest path. Indirectly means not following a straight/shortest path.
Which radioisotope among the following has the shortest half-life?
The radioisotope with the shortest half-life among the following options is Polonium-214.
Which of the following color has the shortest wavelength?
Violet has the shortest wavelength while red has the longest.
Which of the following new world colonies had the shortest life?
new netherland
Do all isotopes have the same half lives?
Yes, all elements have at least one radioactive isotope. Hydrogen has two isotopes, Deuterium and Tritium. H3 has a half life of 12.3 years. Not all isotopes are radioactive. About half way up the atomic mass table, Tin appears to have the greatest number of stable isotopes - ten out of about 124 isotopes in all.
What color of the spectrum has the second shortest wavelength?
According to (longest wavelength) ROYGBIV (shortest wavelength), it would be "indigo."
What type of EM radiation has the shortest wave length and the most energy?
Gamma rays have the shortest wavelength and the highest energy of all types of electromagnetic radiation. They are produced by radioactive decay and nuclear explosions.
Does uranium 238 have the shortest half life?
No, uranium-238 has a long half-life of about 4.5 billion years. It is a naturally occurring isotope that is commonly found in nature. Shorter-lived isotopes, such as radon-222 or polonium-214, have much shorter half-lives.
How long did it take for xenon to decay into cesium?
Most isotopes of Xenon are stable and so do not decay. The shortest lived isotope has a half life of more than 10^16 (10 quadrillion) years.
