Learning Outcomes

In this free course, you will learn how to:

• Describe the atom, the atomic number (Z), the mass number (A), isotopes and ions
• Discuss the structure of atoms and their subatomic particles: protons, neutrons and electrons
• Recognise the long and the short form of the electronic configuration
• Define 'relative atomic' and 'molecular masses', the 'mole' and 'Avogadro's Constant'
• Identify and write a chemical equation, its parts and the steps to balance chemical equations
• Summarise the factors that affect the strength of the metallic bonds and the properties of metals
• Outline the links between chemical bonding and physical characteristics and solubility of substances
• Define 'enthalpy' and the various types of enthalpy changes
• Summarise the concepts of matter, elements and compounds and their properties
• Explain the relation between the mole used to describe the amount of chemical substance and concentration
• Explain how to write the relative formula mass and calculate accurate relative atomic mass using a mass spectrometer
• Outline lattice energy and lattice enthalpy, and use Hess's Law to calculate the overall enthalpy change of a reaction
