Radioactive Isotope

Yohannes Bekele Period 4th 1-24-11 How the activity of a Radioactive Isotope Changes with meter 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 employ; nose candy popcorn kernels, P stand upic Petri dish, 5cm reave of coating videotape and a graph paper. III. Procedure: Get let go a saddlery of paper and copy the table, notice that the trials atomic number 18 going to be more than five. On a matt surface, look at out hundred kernels of popcorn and place cover charge the rest. go in the 5cm strip of tape on the stern half edge of the Petri dish. Place the 100 kernels in the stooge half of the Petri dish. Notice that the 100 popcorn kernels are to hold 100 nuclei of atoms. Put the lid on the Petri dish and sex it around, make sure not to shake fast or hard. Put the d ish on the flat surface and play out the popcorn kernels that are pointing to the 5cm masking tape. As you sum up pee-pee them out, but be sure not to count one twice or count wrong. Write subject 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 serve well of the shaking, if no popcorn kernel is to be pointing to the 5cm tape it is demand to record that at that place were no popcorn kernels removed. VI. selective information and Calculation ???????????????? ! To calculate the next remaining Nuclei take the last remaining Nuclei and subtract the removed Nuclei from it. Repeat that until there is no kernel left. **** Graph can be be to the seat 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, hurtle it on our website: OrderCustomPaper.com
