The carbon-14 atoms undergo beta-minus decay (electron emission) and produce a beta particle and a nitrogen-14 atom. A neutron in the atom undergoes decay and will produce a proton, electron (the beta particle ) and an electron antineutrino. The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.
The carbon-14 it contained at the time of death decays over a long period of time, and the radioactivity of the material decreases.In a first-order reaction, every half-life is the same length of time. Calculate the half-life for the hydrolysis reaction under these conditions.If a freshly prepared solution of cis-platin has a concentration of 0.053 M, what will be the concentration of cis-platin after 5 half-lives? What is the percent completion of the reaction after 5 half-lives? Given: rate constant, initial concentration, and number of half-lives Asked for: half-life, final concentrations, and percent completion Strategy: at 650°C.They have their work cut out for them, however, because radiocarbon (C-14) dating is one of the most reliable of all the radiometric dating methods.This article will answer several of the most common creationist attacks on carbon-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon).
