Radioactive Isotope

Yohannes Bekele Period 4th 1-24-11 How the activity of a Radioactive Isotope Changes with clip I. offer: Since atoms or their nuclei cannot be seen by the eye, it may be utile to model radioactive decay. Using the model, examine how radioactive decreases with time. II. existent: In this experiment the following materials argon utilize; nose candy popcorn kernels, P exsertic Petri dish, 5cm reave of natural covering videotape and a graph paper. III. Procedure: Get expose a saddlery of paper and copy the table, notice that the trials are going to be more than five. On a flat tire surface, opine out hundred kernels of popcorn and place abide the rest. go in the 5cm strip of tape on the roll in the hay half edge of the Petri dish. Place the 100 kernels in the fundament half of the Petri dish. Notice that the 100 popcorn kernels are to construe 100 nuclei of atoms. Put the lid on the Petri dish and wave it around, make sure not to shake fast or hard. Put the dish on the flat surface and computation out the popcorn kernels that are pointing to the 5cm masking tape. As you cast pee-pee them out, but be sure not to count one twice or count wrong. Write overpower how many popcorn kernels were pointing to the tape ( decayed nuclei) and the number of (un decayed) kernels on the table. Repeat the shaking and counting until at that place is no more popcorn kernels left in the Petri dish.

In the put to work of the shaking, if no popcorn kernel is to be pointing to the 5cm tape it is extremity to record that at that place were no popcorn kernels removed. VI. information and Calculation ?????! ??????????? To calculate the next remaining Nuclei take the last remaining Nuclei and subtract the removed Nuclei from it. Repeat that until thither is no kernel left. **** Graph can be be to the dressing of the packet.**** V. Result and Analysis When the time equal zero there were 100 popcorn kernels in the Petri dish. As the time went on the number of kernels started to decrease. The...If you want to get a full essay, throw up it on our website: OrderCustomPaper.com
