WebApr 11, 2024 · Abstract. Since the start of the 21st century, the widespread application of ion probes has promoted the mass output of high-precision and high-accuracy U‒Th‒Pb geochronology data. Zircon, as a commonly used mineral for U‒Th‒Pb dating, widely exists in the continental crust and records a variety of geological activities. Due to the … WebTogether, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number. A property closely related to an atom’s mass number is its atomic mass.
