![CLAMM: (Answer the question.)
The half-life is about 11 seconds.
EVIDENCE: (Point readers to the part of the image that supports your claim.)
On the y-axis when undecayed nuclei is 50%, it means 50% of the nuclei has
reacted and it gives the half-life of the isotope.
REASONING: (Define half-life and use the definition to support why you
pointed to a specific part of the image to make your claim.)
Half-life is the time it takes for half of the original amount of a radioactive
sample to decay.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F41fa5850-a102-4948-aaaf-978cc20b326b%2Ff6b4ea1b-523a-4e7f-9024-b239f1971eae%2Fppk0ucsb_processed.jpeg&w=3840&q=75)

Step 1
Half life is the time during which the half of the radioactive material ( nuclei) get destroyed.
So first of all we have to locate the amount of radioactive material ( nuclei) and need to find it's quantity at 50%
So point y-axis at 50 %
Now, move the pointer towards time axis (x-axis) and note the time.
