Physical Science 513 Unit – Atoms and Elements. Atomic notation X A Z X = Symbol (C, Au) A = Atomic Mass Number = #nucleons (Protons + Neutrons) Z = Atomic Number = #protons C 12 6 Carbon A = 12, Z = 2. What are isotopes? Use two particles from the table above to illustra...
Mass Number (A): • The sum of the protons and neutrons in the nucleus. A=#p + #n Notation Other ways to write elements: 36 17 Cl Cl-36 Atomic Number Mass Number Mass Number Nucleons: protons and neutrons Isotopes of an element have different mass numbers because they have different...
Mass Number Number of protons & neutrons combined Always a whole number Finding the Number of Neutrons Neutrons = mass # - atomic # Example: Oxygen’s mass number is 16 and its atomic number is 8. The number of neutrons will be 16-8 = 8. Isotopes Atoms with the same number of protons...

elements which have odd atomic numbers will have one or two stable isotopes whereas elements with even atomic numbers will mostly have 3 or more stable isotopes. however, there are also exceptions like carbon, helium, and beryllium. an isotope is usually denoted or identified by the name of th...
In subject area: Physics and Astronomy Stable isotopes are specific forms of elements that have the same number of protons but different numbers of neutrons in their nucleus. These isotopes have different atomic weights but maintain the same atomic number. They are valuable in studying processes suc...
What are Isotopes and Isobars in Chemistry? Learn about the difference between the isotopes and isobars, atomic number and mass numbers only @Byju's
The Global Network of Isotopes in Precipitation (GNIP), administrated by the International Atomic Agency, has been archiving precipitation isotope data for several decades14. The Global Network of Isotopes in Rivers (GNIR) is another public data depository developed recently for archiving isotopic ...
