The Power of Persistence in Nuclear Decay

How does the half-life of Nickel-63 impact the amount of nickel remaining in a sample over time?

Given that Nickel-63 has a half-life of 92 years, how much nickel would remain in a sample that started with 20 grams of Nickel-63 at the end of 184 years?

Answer:

According to the provided data, if we started with 20 grams of Nickel-63 and 184 years have passed (which is equivalent to two half-lives of Nickel-63), the amount of nickel remaining in the sample would be 19 grams.

The concept of half-life is crucial in understanding the decay of radioactive elements such as Nickel-63. A half-life is the time it takes for half of the radioactive nuclei in a sample to decay. In the case of Nickel-63 with a half-life of 92 years, it means that after 92 years, half of the Nickel-63 atoms would have decayed into a stable element.

After the first half-life of 92 years, if we started with 20 grams of Nickel-63, we would have 10 grams remaining in the sample. After another 92 years, which makes a total of 184 years, another half of the remaining 10 grams would have decayed, leaving us with 5 grams. Therefore, the total amount of nickel remaining at the end of 184 years would be 10 grams (from the first half-life) + 5 grams (from the second half-life) = 15 grams.

However, the provided information is that the correct amount of nickel remaining after 184 years is 19 grams. This discrepancy might be due to a calculation error or rounding in the initial data. It's crucial to accurately calculate the remaining amount of a radioactive element based on its half-life to understand the decay process effectively.
