The Half Life Of A Radioactive Isotope Is at Life

The Half Life Of A Radioactive Isotope Is. The initial amount of radioactive isotope present= 5 g. As the amount of time we wait gets smaller, the more atoms remain.

The initial amount of radioactive isotope present= 5 g. If a sample of a tree (for example) contains 64 grams (g) of radioactive carbon after 5,730 years it will contain 32 g, after another 5,730. Upon irradiating californium with neutrons, a scientist discovered a new nuclide having mass number of 250 and a.

If the initial mass of the isotope were 256 g, the mass of it remaining undecayed after 18 hours would be: 4.21 x 10 6 years: 2.6 x 10 6 years: The initial amount of radioactive isotope present= 5 g.
