Understandings:
3.1.U1: Atoms of elements have unique structures arising from interactions between electrons and nuclei.
3.1.U2: Atoms are so small that they are difficult to study directly; atomic models are constructed to better visualize and understand the structure of an atom.
3.1.U3: In nature, atoms either gain, lose, or share electrons to attain a state of highest stability.
Skills:
3.1.S1: Determination of an element’s subatomic particles by using the periodic table.
3.1.S2: Calculations of the average atomic mass of an element based on isotope data. (Practical)
3.1.S3: Drawings of ion formation using the Bohr Model or Lewis Dot to depict a gain/loss of electrons.
Nature of Science:
3.1.NOS: As the model of an atom is a theoretical construct rather than an exact description of the atom, any model of the atom is subject to refinement and change in response to new experimental results.
