What is the half life of astatine?
Astatine has many isotopes, each with its own half life. The longest in my list is At209 at 8.1 hours, and At215 is listed at 0.1 ms. The shortest are just listed as 'short' reflecting the small quantities.
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
What is the term given to the time it take for one half of a sample of radioactive nuclei to decay?
The term is called half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
What is the longest radioactive halflife?
First, it isn't very accurate to talk about a radioactive "element"; you should talk about radioactive isotopes. Different isotopes of the same element can have very different behavior in this sense. For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years).Individual atoms, in a radioactive isotope, will decay at a random moment. The half-life refers to how long it takes for half of the atoms in a given sample to decay (and convert to some other type of isotope).
What does Pu-239 has a half-life of?
Pu-239 has a half-life of 24,110 years.
What kind of radioactive waste has the longest half-life?
Uranium has the longest half-life element
What is longest acting insulin?
Longest acting insulins iclude insulin glargine and insulin ultralente
What radioactive substance has the longest half-life?
One of the radioactive substances with the longest half-life is thorium-232, with a half-life of about 14 billion years. Another example is uranium-238, which has a half-life of about 4.5 billion years.
What has the longest half-life?
I believe it is selenium 82 with a half life of 1.3*10 to the 20 years or 130 quintillion years!
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 half-life of the chemical element Flerovium?
The longest-lived isotope currently known is 289Fl with a half-life of ~2.6 s, although there is evidence for a nuclear isomer, 289bFl, with a half-life of ~66 s, that would be one of the longest-lived nuclei in the super-heavy element region.
When do you take Insulin glargine?
10pm
What unstable isotope has the longest half-life?
Tungsten 184 has a half life of nearly 9 sextillion years - which is several trillion times the age of the universe.
How long is ununquadium's half life?
Ununquadium is still being explored. There are 5 confirmed isotopes, and what looks looks two isomers. The longest half-life appears to be 114289Uuq at 2.6 seconds, and the longest isomer appears to be 114289mUuq at 1.2 minutes.
What is the half-life of the chemical element Livermorium?
the longest-lived isotope has lived just 61 ms.
Rutherfordium protons and neutrons?
Rutherfordium has 104 protons; the isotope with the longest half-life (263Rf) has 159 neutrons.
How long does seaborgium last?
The longest half life for a seaborgium isotope is a little more than 2 minutes.
