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 atoms v 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.

Step-by-step explanation:

Sorry if wrong

Answer 2

1. atom

2. 0.5n

Step-by-step explanation:

Because half of the atom's nuclei will decay during each cycle.
