Drawing Conclusions

Having studied the data for patterns and trends, you should now be able to draw some conclusions about how knowing the half-life of the element Lokium would help you determine the absolute age of rock in which this element is found. In a paragraph, create an imaginary example of finding a given amount of Lokium and DOL in a rock, and then determining the absolute age of that rock. Assume that each trial represents 1,000 years.

Knowing the half-life of the element Lokium would certainly be instrumental in determining the absolute age of a rock in which this element is found. Let's imagine a scenario where a rock sample is discovered containing a known amount of Lokium and its decay product, DOL. For instance, suppose we initially find 100 grams of Lokium and 100 grams of DOL in the rock. Using the known half-life of Lokium, let's say it decays into DOL every 1,000 years. After another 1,000 years (1 trial), half of the Lokium would have decayed into DOL, leaving us with 50 grams of Lokium and 150 grams of DOL. If we continue this pattern, after another 1,000 years (2 trials), we would have 25 grams of Lokium and 175 grams of DOL, and so forth. By analyzing the ratio of Lokium to DOL in the rock sample, we can estimate the number of trials that have taken place and thus determine the absolute age of the rock. This method allows us to accurately age the rock based on the decay of Lokium over time, demonstrating the significance of knowing the half-life of this element in dating geological specimens.

Knowing the half-life of the element Lokium would greatly assist in determining the absolute age of a rock in which this element is found. For instance, let's consider an imaginary example where a sample of rock contains a certain amount of Lokium and its Daughter Isotope (DOL), which is the element formed after Lokium undergoes radioactive decay. Through careful analysis, scientists can measure the ratio of Lokium to its DOL in the rock sample. Suppose that after an initial measurement, it is found that the rock contains 4 grams of Lokium and 12 grams of its DOL. This 4:12 ratio signifies that one-half of the original Lokium has decayed, as the half-life of Lokium is known to be 1,000 years in this example. By using this information, it can be concluded that if one-half of the Lokium has decayed over 1,000 years, then the total amount of Lokium needed for the original ratio was 8 grams (as 4 grams is half of 8 grams). Thus, based on the known half-life, scientists can estimate that the rock is approximately 1,000 years old.
