A half-life is the time it takes for half the parent radioactive element to decay to a daughter product. Radioactive carbon-14 is present in the atmosphere and all living things, which absorb it. Upon death a plant or animal no longer absorbs carbon 14 and its amount starts to decrease through radioactive decay so that after 5730 years there is only half the amount of carbon 14 that would be expected in a living plant or animal.
1. Use the info to conjecture a model for the number of carbon-14 atoms that have not decayed from an initial number.
could someone please help me with this, i really have no idea how to do it
