...arching soldiers, said Pochapsky. The electrons, neutrons
and protons within the atom have an intrinsic property known as "spin" and within the electromagnetic field created by the magnet, the frequency of the spinning motion of the atoms reveals information about the physical, chemical, structural and elec...

...re--12C, 13C and 14C. They differ in the number of neutrons
in the nucleus. By far the most abundant variety is in the lightest, 12C. About 1% is 13C, a heavier sibling with an additional neutron. There is even less 14C, the unstable, radioactive heavyweight of them all. "13C is the key," Fogel explained. "T...
