• Describe the charge, relative mass, and the location of protons, electrons, and neutrons within an atom.
• Calculate the number of protons, neutrons, electrons, and mass number in neutral atoms and ions.
• Explain how the different mass numbers of isotopes contributes to the average atomic mass for a given element (conceptual, no
calculations).
• Use isotopic notation to write symbols for various isotopes (ex. Carbon-12, C-12, 12C, etc.)
• Explain Bohr’s model of the atom.
• Draw Bohr models from hydrogen to argon including common isotopes and ions.
• Construct dot diagrams, a shorthand notation for Bohr models, using the element symbol and dots to represent electrons in the
outermost energy level.
