Chemistry is the study of matter what it's made of how it behaves and the changes it undergoes including energy transformations. This diploma course in chemistry introduces you to these fascinating areas of chemistry. We begin by exploring atoms and the elements that derive from a single atom. This course will guide you through representing atoms using symbols atomic and mass numbers. You will explore isotopes and their properties. You will gain a clear understanding of shells subshells electronic configurations and ionisation energy before exploring the three states of matter and their properties.The following section delves into moles and equations. We demonstrate how a mass spectrometer helps accurately calculate an element's relative isotopic mass. We teach you how to calculate reacting masses the volume of solutions or gases and the concentration of a solution to deduce the stoichiometry of a reaction. We explain the three types of chemical bonding: ionic covalent and metallic and look at the relationship between bond energy and bond length.Enthalpy change and Hess's law come next. You'll learn to compare the enthalpies of different reactions before discovering the method to measure and calculate enthalpy changes using a calorimeter and the enthalpy cycle. You will analyse the variables that affect lattice energy and enthalpy change. This course will enable you to develop the skills and abilities required to begin your AS chemistry journey.
