: Half-life is constant for a specific isotope and cannot be changed by physical or chemical means.
A common method for finding half-life is using a decay curve (activity vs. time). : Locate the starting point ( N0cap N sub 0 ) on the vertical axis (y-axis). Calculate Half-Value : Divide the initial activity by 2 ( Half-Life-Alyx-TRNT.rar
: You cannot predict when a single nucleus will decay, but you can predict the behavior of a large sample. : Half-life is constant for a specific isotope
) of a radioactive isotope is the time required for half of the unstable nuclei in a sample to undergo radioactive decay. : Half-Life-Alyx-TRNT.rar
