If 50% of a radioactive element remains after 4000 years, what is the half-life? 1,2,3, or 4 half-life(s)

5 answers

If 50% of a radioactive element remains after 4000 years, it indicates that one half-life has passed. A half-life is the time required for half of a radioactive substance to decay. Therefore, in this scenario, the half-life of the element is 4000 years.

So, the answer is 1 half-life.

Question 8 (1 point) What is the half-life of Candium? (i.e., What number of shakes are necessary to reduce the radioactive members to one-half?)

The specific half-life of Candium (if you're referring to the hypothetical element) is not widely recognized in scientific literature, as "Candium" isn't a standard term or element in the periodic table. If you're referring to a fictional or specific example in a textbook or study, the half-life would be provided in that context.

To answer your query properly, I would need more information about the context in which Candium is mentioned or any specific details associated with it. If you have data or specific figures regarding its half-life, please provide that, and I can help you analyze it!

a. 6 million (6 seconds of shakes)
b. 813 million years (8.13 seconds or shakes)
( c. 713 million (7.13 seconds of shakes)
The m and m data graph thing

It appears you're referring to a hypothetical or fictional element called "Candium" and its related half-life. Based on the options you provided, it seems that you are looking for which of these choices represents the half-life of Candium.

If the context involves a radioactive decay graph or simulation where "shakes" represent time intervals (similar to half-lives), you would select the choice that best fits the scenario being described.

From what you've provided:

  • Option a suggests 6 million years with 6 seconds of shakes.
  • Option b suggests 813 million years with 8.13 seconds of shakes.
  • Option c suggests 713 million years with 7.13 seconds of shakes.

Without additional context regarding the properties or behavior of Candium, it’s hard to definitively choose the correct option. Generally, the half-life should align with the data or experiments referenced in your materials.

Determining the Half-Life

  • If your materials refer to the half-life being represented as a very long duration, options b (813 million years) and c (713 million years) are more likely candidates than option a (6 million years).

Choose the option that aligns with the data or graphical representation in your course or study materials. If it specifically indicates the half-life being over hundreds of millions of years, then either b or c is likely your answer.
