How has the model of atomic structure changed over time?
By the end of this unit, you will be able to:
- Describe how atomic models have changed over time as new experimental results have led to new theories about the structure of the atom. Description includes experimental evidence that has led to changes, the construction of representations, comparison and contrast of models, and identification of the factors that have stayed consistent and the ones that have changed.
- Use data consisting of symbolic representations (e.g., 11Na+) or numbers of subatomic particles for various atoms, isotopes or ions.
o Make a claim, based on the number of protons, about which species are atoms of different elements, and identify the elements.
o Make a claim, based on the number of protons and electrons, about which species are ions, and identify the ions.
o Make a claim, based on the number of protons and neutrons, about which species are isotopes of the same element, and identify the element of which they are isotopes.
o Explain, using the concept of isotopes, why atomic masses are not expressed as whole numbers.
o Calculate atomic masses. Calculations are based on isotopic abundances. - Explain, in terms of the mobility of electrons, how the charged nature of matter produces measurable and observable effects (e.g., static electricity, lightning) on the macroscopic scale.
