In this half-life worksheet, students determine how long it takes for a 100g sample of AU-198 to decay to 6.25g. Then they determine the half-life of a radioactive isotope if a 500.0g sample decays to 62.5g in 24.3 hours. Students also...

Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...

In this half-life worksheet, learners use a given table of half lives, mass, time and amount of original sample to solve for unknowns in nine given half-life problems.

In this nuclear chemistry worksheet, students answer ten questions about radioactive decay, half life, electron capture and alpha emission.

In this nuclear chemistry learning exercise, students solve nine problems about half life, positron emission, nuclear fission and nuclear fusion.

In this radioactivity worksheet, high schoolers answer 40 questions about half life, isotopes, radioactive decay, the uses of radioactivity, nuclear equations and the scientists associated with radioactivity.

In this nuclear chemistry worksheet, students evaluate data from concentration experiments on radioactive iodine. They graph the data, determine radioactive decay and half life for the element.

In this radioactivity worksheet, students write the mass number and atomic number for the missing element in the reactions. Students identify the isotope that is more stable and determine the half-life of the isotope. This worksheet has...

In this nuclear chemistry worksheet, students answer 9 questions. They balance nuclear equations, they write balanced equations, they calculate decay and they find binding energy of atoms.

In this reaction rate worksheet, students determine the molecularity of a reaction plus show that the predicted rate law equals the experimental rate law. This worksheet has 3 problems to solve.

In this atoms worksheet, students review terms associated with atoms which includes isotopes, transmutation, and radioactive decay. This worksheet has 11 short answer questions.

In this radioactivity quiz worksheet, learners complete a 10 question true/false quiz. Quiz is also available as a student handout and Powerpoint presentation.
