Question

The half-life period of a radioactive element is 100 seconds. How much time will it take for 90 % decay? please answer sincerely (the answer is 332.3, I need the method)

Answer 1

Answer:

Each radioactive material has a decay rate. The time that it takes for half of the radioactive atoms to decay is called a half-life. For example, the previously mentioned technetium-99m has a half-life of six hours which means that, starting with 100 percent, after six hours, we will have 50 percent left.

Explanation:

Don't take your health for granted. Don't take your body for granted. Do something today that communicates to your body that you desire to care for it. Tomorrow is NOT promised.
