Respuesta :
The half life for radioactive can be calculated as:
N /N0 = (1 /2) ^ n
n = T /T half
According to question there are n number of half life are present which would result in remaining amount of element as n.
Answer:
Hypothesis: If an element is radioactive, then the fraction of radioactive atoms remaining after n half-life cycles should be approximately 0.5n, because approximately half of the atoms’ nuclei will decay during each cycle.
Explanation: Lab: Half-Life
