The atom of each element is made up of electrons, protons and neutrons all atoms of the same neutral element have the same number of protons and electrons but the number of neutrons can differ atoms of the same element but. This is to write the element name or symbol, followed by the number of protons plus neutrons for example, helium-3 or he-3 is the same as writing 3he or 31he, the most common isotope of helium, which has two protons and one neutron.
In isotopic notation, the mass number of the isotope is written as a superscript in front of the chemical symbol for that element in hyphen notation, the mass number is written after the name of the element. What are isotopes you can think of isotopes as atomic siblings they are part of the same family (same number of protons) but they are unique in that each isotope has a different number of neutrons in its nucleus. Isotope notation subscripts and superscripts can be added to an element’s symbol to specify a particular isotope of the element and provide other important information. Isotopes are different types of atoms of the same element, each having a different mass number isotopes of an element have nuclei with the same number of protons (the same atomic number), but different numbers of neutrons.
