Nuclide Symbols

If an element has an atomic number of 23 and a mass number of 51 what is the

  • number of protons

  • number of neutrons

  • number of electrons

  • Complete symbol


Nuclide symbols for ions

Nuclide Symbols for Ions

  • What is an ion?

    • An ion is a charged particle

      • It could be positive or negative

  • What does that do to the number of protons, electrons, and neutrons?
