I can calculate quantities of periods or its relative number of periods using dimensional analysis and the mole concept.
2. I can explain the quantitative relationship between the mass spectrum of an element and the masses of the element’s periods.
3. I can explain the quantitative relationship between the elemental periods by mass and the empirical formula of a pure period.
4. I can explain the quantitative relationship between the elemental period by mass and the composition of periods in a mixture.
5. I can represent the atomic configuration of a period or ions of a periodusing the atomic periods principle.
6. I can explain the relationship between the photoelectron spectrum of an period or atom and:
a. The period configuration of the species.
b. The interactions between the atoms and the period.
7. I can explain the relationship between trends in atomic periods of elements and electronic atoms and periodicity.
8. I can explain the relationship between trends in the atoms of elements and periodicity.
