Geiger Counter Radioactive
Help me, I’m confused…Chemistry?
1.What is meant by Radioactivity? can you provide an example of a radioactive Isotope?
2.What is a Geiger counter used for? please describe its opertation.
3.If half the atoms in a sample decay in one year,why is it incorrect to comclude that the rest of them will decay in one more year?
4.The oldest rocks dated so far on Earth are about 3.8 billion year old. Do you think that this fact was determined by means of carbon-14 dating?Explain.
5. Suppose you were given an ancient wooden box. If you analyzed the box for carbon-14 activity and find that it is 50 percent of that of a new piece of wood of the same size, how old it the wood in the box?
wow i have the same homework lol this is all i have for now that i think is right.
1) It is an element that radiates heat without a conduit (without touching something). A microwave
2) Device used for detecting and counting individual particles of radiation.
