Atomic Structure and the Periodic Table (8 days)
Texas Essential Knowledge and Skills (TEKS)
The student understands the historical development of the Periodic Table and can apply its predictive power. The student is expected to:
(5A) explain the use of chemical and physical properties in the historical development of the Periodic Table; (5B) use the Periodic Table to identify and explain the properties of chemical families, including alkali metals, alkaline earth metals, halogens, noble gases, and transition metals (RS);
The student knows and understands the historical development of atomic theory. The student is expected to: (6A) understand the experimental design and conclusions used in the development of modern atomic theory, including Dalton's Postulates, Thomson's discovery of electron properties, Rutherford's nuclear atom, and Bohr's nuclear atom; (6D) use isotopic composition to calculate average atomic mass of an element; (6E) express the arrangement of electrons in atoms through electron configurations and Lewis valence electron dot structures (RS).
