11 C, used as a tracer in PET scans and C, used in dating organic materials are unstable isotopes of carbon. Calculate the N/Z ratio and write balanced spontaneous decay reactions for both atoms.
Expert Answer
The ratio of number of neutrons to number of protons in an atomic nucleus gives the N/Z ratio.
The N/Z ratio of the C-11 isotope is calculated by identifying the number of neutrons and number of protons in it.
The N/Z ratio of the C-14 isotope is calculated by identifying the number of neutrons and number of protons in it.
For both isotopes, the N/Z ratio is low which indicates that they are below the band of stability. These types of isotopes decay either by electron capture or by positron emission since...
