What is the half life of uranium 235?

What is the half life of uranium 235?

The half-life of uranium 238 is of 4.5 billion years, while uranium 235 has a half-life of 'only' 700 million years.

How does half life work?

Half Life. The amount of time it takes a radioactive isotope to decay into a stable isotope is different for each radioactive isotope, and is characterized by its “half-life”. An isotope's half-life is the amount of time it takes for half the number of atoms of that isotope to decay to another isotope.

What is the radioactive decay formula?

The rate of nuclear decay is also measured in terms of half-lives. The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days.
