UNITS 4&14- STRUCTURE AND BONDING

Essential ideas:

• Ionic compounds consist of ions held together in lattice structures by ionic bonds.
• Covalent compounds form by the sharing of electrons.
• Lewis (electron dot) structures show the electron domains in the valence shell and are used to predict molecularshape.
• The physical properties of molecular substances result from different types of forces between their molecules.
• Metallic bonds involve a lattice of cations with delocalized electrons.
• Larger structures and more in-depth explanations of bonding systems often require more sophisticatedconcepts and theories of bonding.
• Hybridization results from the mixing of atomic orbitals to form the same number of new equivalent hybridorbitals that can have the same mean energy as the contributing atomic orbitals.
