WebThe mass number, also called the nucleonnumber, is the number of protonsand neutronsin an atomic nucleus. The mass number is unique for each isotopeof an element and is written either after the element name or as a superscript to the left of an element's symbol. For example, carbon-12(12C) has 6 protons and 6 neutrons. Nominal mass[edit] Web19 de dic. de 2024 · Mass spectrometry is a technique used to measure the mass and relative abundance of ions in a sample. This technique produces a graph, called the mass spectrum, that allows us to identify different isotopes of an element and the relative abundance of each isotope in nature. Mass Spectrum of Carbon
