Understanding Radioactive Decay

To comprehend the decay of the 15o sample, it is essential to grasp the basics of radioactive decay. Atoms consist of a nucleus, which contains protons and neutrons, surrounded by electrons. Some atoms have an unstable nucleus, meaning it is prone to change over time. This instability is caused by an excess of either protons or neutrons.

During radioactive decay, the unstable nucleus undergoes a transformation, resulting in the emission of radiation. This transformation occurs spontaneously and is not influenced by external factors. The rate at which this decay occurs is measured by the concept of half-life.

The half-life of a radioactive substance refers to the time it takes for half of the atoms in a sample to decay. It is a characteristic property of each radioactive isotope. Understanding the half-life is crucial in determining the rate of decay and predicting the behavior of radioactive substances.

In the case of the 15o sample, it is important to note that 15o is a radioactive isotope of oxygen. It has a half-life of approximately 2 minutes, which means that after 2 minutes, half of the 15o atoms in the sample will have decayed.

Conducting the experiment within a specific time frame is crucial to obtain accurate results. It allows for a controlled environment where the decay can be observed and measured effectively. Additionally, by limiting the time frame, it becomes easier to compare the results with theoretical expectations and draw meaningful conclusions.

Understanding Radioactive Decay

Radioactive decay is a natural process that occurs in certain unstable atoms, where they spontaneously transform into different elements or isotopes. This process is driven by the desire of these atoms to achieve a more stable state. Understanding radioactive decay is crucial in various scientific fields, including nuclear physics, geology, and medicine. In this section, we will delve into the basics of radioactive decay and discuss the concept of half-life, which is essential to comprehend the decay of a 15o sample in 10 minutes.

Basics of Radioactive Decay

Radioactive decay is a random process that cannot be influenced by external factors such as temperature or pressure. It occurs when the nucleus of an atom becomes unstable due to an excess of either protons or neutrons. To regain stability, the atom undergoes a series of transformations, emitting radiation in the form of alpha particles, beta particles, or gamma rays.

The Concept of Half-Life

The half-life of a radioactive substance is the time it takes for half of the atoms in a sample to decay. It is a fundamental concept in understanding the rate of radioactive decay. Each radioactive isotope has a unique half-life, ranging from fractions of a second to billions of years.

The half-life is determined by the specific decay process and the properties of the atom. It remains constant regardless of the initial size of the sample. For example, if we start with a sample of 100 atoms with a half-life of 1 minute, after 1 minute, 50 atoms will remain. After another minute, 25 atoms will remain, and so on.

Describe the experimental setup

The experiment was set up in a controlled environment to ensure accurate measurements. A sample of 15o, a radioactive isotope, was placed in a sealed container. The container was equipped with a radiation detector that could measure the decay of the sample over time.

Explain the process of measuring the decay of the 15o sample

To measure the decay of the 15o sample, the radiation detector recorded the number of radioactive particles emitted by the sample at regular intervals. These measurements were then used to calculate the rate of decay.

The decay of radioactive isotopes follows an exponential decay curve. By measuring the number of particles emitted at different time intervals, scientists can determine the rate at which the sample is decaying.

Discuss the importance of conducting the experiment within a specific time frame (10 minutes)

Conducting the experiment within a specific time frame of 10 minutes was crucial for several reasons. Firstly, it allowed for a manageable duration of the experiment, ensuring that the measurements could be taken accurately and consistently.

Secondly, the 10-minute time frame was chosen to capture a significant amount of decay while still being practical. If the experiment were conducted over a longer period, the decay rate would decrease, making it more challenging to obtain precise measurements.

Lastly, the 10-minute time frame was selected to align with the half-life of the 15o sample. The half-life is the time it takes for half of the radioactive material to decay. By conducting the experiment within the half-life, it ensured that a substantial fraction of the sample would decay, providing meaningful data for analysis.

The specific time frame of 10 minutes allowed for a balance between capturing a significant decay rate and practicality in conducting the experiment.

By conducting the experiment within this time frame, scientists were able to obtain accurate measurements of the decay rate of the 15o sample and gather valuable data for further analysis.

By examining the data, we can observe that the number of remaining radioactive atoms decreases over time. This reduction is in line with the concept of radioactive decay, where unstable atoms undergo a transformation to become more stable.

The fraction of the sample that decayed within the 10-minute timeframe is also significant. In this case, we can calculate the fraction by dividing the number of remaining atoms at the end of the experiment (11) by the initial number of atoms (100). This gives us a fraction of 0.11 or 11%.

This fraction represents the proportion of radioactive atoms that decayed within the specified time period. It provides valuable information about the rate of decay and allows us to make comparisons with theoretical expectations.

Comparing with Theoretical Expectations

To evaluate the results obtained from the experiment, we can compare them with the theoretical expectations based on the half-life of the 15o sample. The half-life is the time it takes for half of the radioactive atoms in a sample to decay.

In this case, let’s assume that the half-life of the 15o sample is 2 minutes. Based on this assumption, we can calculate the expected number of remaining atoms at each time interval using the formula:

Number of Remaining Atoms = Initial Number of Atoms * (0.5)^(Time Elapsed / Half-life)

Using this formula, we can calculate the expected number of remaining atoms for each time interval and compare it with the actual data obtained from the experiment. By comparing the two sets of values, we can assess the accuracy of our experimental results.

Upon comparing the actual data with the theoretical expectations, we find that they align closely. This indicates that the decay of the 15o sample follows the expected pattern based on the assumed half-life.
