Use the periodic table. Compare atomic structure to the layout of the periodic table. Chapter 9.1 Objectives and Vocabulary Name the subatomic particles that make up an atom and describe their locations. Describe the forces that hold atoms together. Identify the number of particles in an atomic nucleus. atomic theory proton electron neutron charge nucleus electromagnetic force strong nuclear force isotopes atomic number mass number Chapter 9.2 Objectives and Vocabulary Use the periodic table to obtain information about the elements. Explain the relationship between an element's placement on the periodic table and its chemical properties. Understand a simple model of electron arrangement. periodic talbe period group metal nonmetals metalloids energy level valance electrons chemical bond noble gases 9B Investigation: Energy and the Quantum Key Question: How does an atom absorb and emit light energy? *Students read text section 9.3 AFTER Investigation 9B 9B Investigation Topics Build and model atoms. Compare absorption and emission in atoms. Chapter 9.3 Objectives and Vocabulary Explain the meaning of quantum theory. Compare and contrast the Bohr and quantum atomic models.
