How does carbon 14 decay by beta emission?
Solution
Hint : Carbon−14 rots by beta emanation into nitrogen−14. A β−particle is really a quick electron, having a negative charge and no mass. Carbon−14 has 6 protons and 8 neutrons and is radioactive in nature.
Complete Step By Step Answer:
Carbon 14 has 6 protons and 8 neutrons and is radioactive. It has a half-existence of around 5,730 years. This implies that following 5,730 years half of the iotas will have rotted. Carbon 14 is unsteady since it has such a large number of neutrons. It rots by beta discharge where one of the neutrons gets changed over into a proton, an electron and an electron hostile to the neutrino.
614C→714N+e−+ve
The rot is a consequence of the frail power. A proton has 2 up quarks and 1 down quark. A neutron has 1 up quark and 2 down quarks. A down quark in one of the neutrons gets changed over into an up quark and a W− which rots into an electron and an electron against the neutrino.
d→u+W−
W−→e−+νe
A radioactive molecule can rot by emanating a beta molecule which is a quick electron. A characteristic illustration of beta discharge is the rot of carbon-14 into nitrogen-14. The condition for the rot is:
614C→714N+−10β
Notice that the condition adjusts for both the nuclear number and the nuclear mass number. The nuclear mass number doesn't change in light of the fact that a beta molecule has a lot more modest mass than the particle. The nuclear number goes up on the grounds that a neutron has transformed into an additional proton.
Note :
Carbon−14 is precarious on the grounds that it has an excessive number of neutrons. It rots by beta outflow where one of the neutrons gets changed over into a proton of nitrogen, and an electron (e−) or β−particle.
