C (6 protons and 8 neutrons) plus a proton (by-product of the reaction) The decay process involves a spontaneous loss of an electron as a beta particle. Radiocarbon dating is a method of estimating the age of organic material. a nitrogen (seven protons, seven neutrons) atom it turns into a carbon atom to detect the electrons given off by decaying Carbon as it turns into nitrogen. The 14C nucleus has 6 protons plus 8 neutrons, giving it an atomic mass of via a technique called "carbon dating" or "radiocarbon dating".

But sedimentary strata often can be followed to geological faults and other regions where volcanic activity occurred around the same time that the sedimentary rock was deposited. In general, though, an atom's atomic mass will be very close to its mass number, but will have some deviation in the decimal places. In fact, the number of protons determines what atom we are looking at e. The radioactive 40K which is contained in a natural mixture of potassium isotopes begins to decay to 40Ar gas which gets trapped in the crystalline matrix.
