WebCHEMISTRY. PENNIUM LAB. Most elements consist of a mixture of two or more naturally occurring isotopes. (Atoms of an element that vary because they have different mass numbers, numbers of neutrons). Different isotopes of an element have different relative atomic masses due to the different number of neutrons in the nucleus. In this lab you are … http://algebralab.org/activities/activity.aspx?file=Science_AvgAtomicMass.xml
WebStudy with Quizlet and memorize flashcards containing terms like After each half-life cycle, _____ of the radioactive nuclei became nonradioactive., During the experiment, the number of radioactive atoms never increased because a radioactive nucleus _____ becomes radioactive again after it decays., Your simulation involved 100 atoms and eight half-life cycles. Webof each isotope. 6. Multiply the relative abundance from Step 5 by the average mass of each isotope to get the relative weight of each isotope. 7. Add the relative weights to get the average mass of all particles in vegium, the atomic mass. Note: When you weigh the various isotopes of vegium, you may encounter some problems.

WebLab: Half Life of Pennium Background: Some naturally occurring isotopes of elements are not stable. They slowly decompose by discarding part of the nucleus. The isotope is said to be radioactive. This nuclear decomposition is called nuclear decay. The length of time required for half of the isotope to decay is the substance's half-life.
