What is an isotope? When an atom of a given element has the same number of protons, but differs in the number of neutrons,. What does the number next to isotopes signify? The atomic mass signifies the number next to the isotope. How can you tell isotopes of the same element apart? Isotopes will have a different atomic mass than other atoms that make up the same element. For each of the following isotopes, write the number of protons, neutrons, and electrons.

The development of modern atomic theory revealed much about the inner structure of atoms. It was learned that an atom contains a very small nucleus composed of positively charged protons and uncharged neutrons, surrounded by a much larger volume of space containing negatively charged electrons. Atoms—and the protons, neutrons, and electrons that compose them—are extremely small. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit amu and the fundamental unit of charge e. The atomic mass unit amu was originally defined based on hydrogen, the lightest element, and oxygen. Because of this ambiguity it was redefined in as the unified atomic mass unit u with regard to the most abundant isotope of carbon, atoms of which are assigned masses of exactly 12 u. The Dalton Da and the atomic mass unit amu are alternative units that are almost identical to the u. A proton has a mass of 1.
