The molecular world

Course learning outcomes

After studying this course, you should be able to:

• explain what is meant by isotopes, atomic numbers and mass numbers of the atoms of chemical elements by referring to the Rutherford model of the atom
• give an example of how differences in the molecular structures of chemical compounds give rise to differences in macroscopic properties
• indicate ways in which the chemical periodicity represented by a Periodic Table matches the periodicity in the electronic structure of atoms
• use the Lewis structures of one or two simple chemical substances to illustrate the ideas of the octet rule, the electron-pair bond and the valence-shell repulsion theory of molecular shape
• select a set of organic molecules, each of which contains the same functional group, and use its reactions to show why the functional group concept is useful.
