Because these rates do not change and because the radiation that rocks give off can be measured, it became possible to calculate the time the rock was formed or, in other words, the rock's birth date - give or take a few thousand years or so.Radiometric dating is sometimes referred to as radioactive dating.In this fast-paced, demanding course, the main topics--which include atomic theory, nuclear chemistry, periodicity, chemical reactions, stoichiometry, gases, solutions, reaction kinetics, equilibrium, acid-base theory, oxidation-reduction, and organic chemistry--are studied at an advanced level, with an focus on both conceptual understanding and problem-solving.Quantitative aspects of chemical concepts are emphasized throughout the course.This is the second lesson in a three-lesson series about isotopes, radioactive decay, and the nucleus.The first lesson, Isotopes of Pennies, introduces the idea of isotopes.Learn about three common types of radioactive decay: alpha decay, beta decay and gamma decay. You simply subtract your birth date from the current date. It was also discovered that these elements decayed into other elements at fixed rates.

Our textbook Introductory Chemistry: A Foundation 7e (Zumdahl and De Coste) Questions? (This will be strictly enforced.) If you need advice on selecting or using a suitable calculator, ask Dr. First, we will study reaction rates, using collision theory as the guiding principle.

Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.

However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.

Laboratory experimentation is an integral part of this class, and students write a number of formal reports which require demonstration of a sophisticated understanding of the relevant theories and principles.

Students are expected to work cooperatively in both laboratory and classroom settings and to take individual responsibility for meeting the objectives of the course.
