Unit 4: Periodicity & Bonding
Key Skills:
- Explain the use of chemical and physical properties in the historical development of the Periodic Table
- 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
- Use the Periodic Table to identify and explain periodic trends, including atomic and ionic radii, electronegativity and ionization energy
- Understand the electromagnetic spectrum and the mathematical relationships between energy, frequency, and wavelength of light
- Calculate the wavelength, frequency and energy of light using Planck's constant and the speed of light
- Express the arrangement of electrons in atoms through electron configurations and Lewis valence electron dot structures
- Construct electron dot formulas to illustrate ionic and covalent bonds
- Describe the nature of metalling bonding and apply the theory to explain metallic properties such as thermal and electrical conductivity, malleability and ductility
- Predict molecular structure for molecules with linear, trigonal planar, trigonal pyramidal, or tetrahedral electron geometries abd their variances using Valence Shell Electron Pair Repulsion (VSEPR) theory
