Unit 4.2:  Bonding

All chemical changes are chemical reactions.  All chemical changes involve the breaking of chemical bonds, the re-arrangement of atoms, and the forming of new chemical bonds.  This makes the types of chemical bonds one of the major focal points of chemistry.  This unit studies metallic bonding, ionic bonding, and covalent bonding.  This unit also explores the theory and shapes associated with covalent bonding as explained by Valence Shell Electron Pair Repulsion (VSEPR) Theory.  Students will also be introduced to the polarity of VSEPR shapes and Intermolecular Forces (IMF's).

 

TEKS:

C.7 The student knows how atoms form ionic, metallic, and covalent bonds. The student is expected to:

    C.7C   construct electron dot formulas to illustrate ionic and covalent bonds

    C.7D  describe the nature of metallic bonding and apply the theory to explain metallic properties such as thermal and electrical conductivity, malleability, and ductility

    C.7E  predict molecular structure for molecules with linear, trigonal planar, or tetrahedral electron pair geometries using Valence Shell Electron Pair Repulsion (VSEPR) theory
