Radioactive Isotope

Yohannes Bekele Period 4th 1-24-11 How the activity of a Radioactive Isotope Changes with clipping I. offer: Since atoms or their nuclei cannot be seen by the eye, it may be utile to model hot 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 weatheric Petri dish, 5cm reave of mask videotape and a graph paper. III. Procedure: Get publication a saddlery of paper and copy the table, notice that the trials are going to be more than five. On a level surface, compute out hundred kernels of popcorn and place blanket the rest. go in the 5cm strip of tape on the hind end half edge of the Petri dish. Place the 100 kernels in the asshole half of the Petri dish. Notice that the 100 popcorn kernels are to instance 100 nuclei of atoms. Put the lid on the Petri dish and handshaking it around, make sure not to shake fast or hard. Put t he dish on the flat surface and find out out the popcorn kernels that are pointing to the 5cm masking tape. As you take care 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 process of the shaking, if no popcorn kernel is to be pointing to the 5cm tape it is get hold of to record that at that place were no popcorn kernels removed. VI. informa tion 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 O.K. 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, entrap it on our website: OrderCustomPaper.com
