Be sure to turn them in when y ousubmit y our lab report.1. How is a r adioactive element diff erent fr om a stable element?The r adioactiv e element s nucleus emits beta, alpha, or gamma r adiation. Astable element has a nucleus that does not emit these par ticles.2. What information does a r adioactive element' s half-life tell you about thatelement?It tells me how long it tak es for one-half of the radioactive isotope to deca y.3. Imagine that a r adioactive isotope has a half-lif e of 2 years. A sample contains1000 at oms of the r adioactive isotope. Complete the following table t o predict howmany at oms of the r adioactive isotope remain in the sample o ver time.Time elapsed (y ears)Number of r adioactive atoms r emaining01000250042506125862.51031.25This study source was downloaded by 100000859819779 from CourseHero.com on 02-03-2023 06:07:52 GMT -06:00https://www.coursehero.com/file/171729386/1043-Lab-Radioactivity-and-Radiation-1pdf/4.
