In your case, you know that thorium-234 has a half-life of 24 days. That means that every 24 days, half of the atoms of thorium you have in your sample will decay.02-Dec-2015

What is the half-life of thorium-234?

24.1 days Thorium-234 (half-life = 24.1 days) was first measured in the oceans in the late 1960's by Bhat et al.

How do you find the half-life of an isotope from a graph?

How do you calculate half-life decay?

The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1/2, and the decay constant is given by T1/2 = 0.693/λ.

When an atom of thorium-234 is transmuted into an atom of protactinium-234 what type of decay has occurred?

beta decay The atomic number in the process has been increased by one since the new nucleus has one more proton than the original nucleus. In this beta decay, a thorium-234 nucleus has one more proton than the original nucleus. In this beta decay, a thorium-234 nucleus has become a protactinium-234 nucleus.

What is the half-life of thorium 233?

approximately 21.83 minutes When a nucleus of thorium-232 absorbs, or “captures,” a neutron, it becomes thorium-233, whose half-life is approximately 21.83 minutes. After that time the nuclide decays through electron emission to protactinium-233, whose half-life is 26.967 days.

What is the half-life of isotopes?

The half-life of a radioactive isotope is the amount of time it takes for one-half of the radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.

What does half-life mean in isotopes?

Radioactive half-life is the time required for a quantity of a radioisotope to decay by half. If the half-life of an isotope is relatively short, e.g. a few hours, most of the radioactivity will be gone in a few days.
