Use table 1: analysis of decay in the laboratory guide to answer this question: scientists find a piece of wood that is thought to be from an ancient fire circle. they find that the wood contains an amount of carbon-14 (14c) that is approximately 1/16 of the current atmospheric 14c levels. determine approximately how many years ago the tree was chopped down to be used for the firewood. if you started with 1 million carbon-14 atoms, how many atoms would remain in the wood? 14c has a t1/2 of 5,750 years.
