Unit 2.I: Atomic Structure & Nuclear Chemistry

The smallest particle that defines elements, and possess the properties that explain their chemical and physical properties within the study of Chemistry, is the atom.  This unit studies the history of the development of Atomic Theory, the subatomic particles that result in their properties, isotopes, and average atomic mass.  Additionally, this unit also studies the formation and decay of elements and the energy related to nuclear chemistry.  This unit also covers fission and fusion, and radioactive decay including half life.  It also explores the conservation of mass within nuclear reactions.

 

TEKS:

C.6  The student knows and understands the historical development of atomic theory. The student is expected to

   C.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

   C.6D use isotopic composition to calculate average atomic mass of an element

 

C.12 The student knows the basic processes of nuclear chemistry.  The student is expected to:

    C.12A   describe the characteristics of alpha, beta, and gamma radiation

    C.12B  describe radioactive decay process in terms of balanced chemical equations

    C.12C  compare fission and fusion reactions
