Carbon-14 is a radioactive isotope of carbon. An atom of carbon-14 has 6 in its nucleus. Carbon-14 decays by emitting a beta particle. State what happens to a nucleas of carbon-14 when it emits a beta particle.

Explain what happens to an isotope of carbon-14 that undergoes beta-minus decay with reference to the properties of beta particles, the changes taking place during beta-minus decay and the new element formed.

Carbon-14 is a radioactive nucleus with a half-life of 5760 years. In livingmatter the amount of carbon-14 decays at a rate of 15.3 decay events perminute per gram of carbon. A fossil is analysed and found to have a carbon-14 decay rate of 7.70 decay events per minute per gram of carbon. How oldis the fossil?

An isotope of carbon is:A  an atom of carbon that has an extra protonB  an atom of carbon that has fewer protonsC  an atom of carbon that has extra electronsD  an atom of carbon that has a different number of neutrons*1 pointABCD

Select the correct answer.The amount of a radioactive substance remaining as it decays over time is 𝐴=𝐴0⁢(0.5)𝑡ℎ , where A represents the final amount, 𝐴0 represents the original amount, t represents the number of years, and h represents the half-life of the substance.Carbon-14 is a radioactive isotope that has a half-life of 5,730 years. Approximately how many years will it take for carbon-14 to decay to 10 percent of its original amount? A. 16,396 years B. 19,035 years C. 28,650 years D. 8,267 years

Carbon-14 decays into nitrogen-14 by emitting a – particle.Which statement explains why the – particles are emitted with a range of different kineticenergies?A The carbon-14 nuclei have slightly different masses.B The emitted – particles have a range of different masses.C The energy released in the decay process is different for each carbon-14 nucleus thatdecays.D The energy released in the decay process is shared between the nitrogen-14 nucleus, a– particle and an antineutrino.
