Question

The goal of this lesson is to answer the lesson question, "what does half-life ‘look like' for a radioactive substance?" fill in the blanks to complete the hypothesis. hypothesis: if an element is radioactive, then the fraction of radioactive remaining after n half-life cycles should be approximately n because…

Answer 1

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 2

Atoms

0.5

There are n number of half life are present which would result in remaining amount of element as n.
