Metallic bonding and properties of metals
Metal atoms find it fairly easy (in terms of energy) to lose their outer-shell or valence electrons. They have a

An ionic equation describes the actual chemical reaction that occurs when two solutions are mixed and a precipitate forms (insoluble
Ionic bonding is the electrostatic attraction between oppositely charged ions – it is not the transfer of electrons from one
Mass spectrometry is a really powerful tool for helping us to piece together the structure of an organic molecule. Ionisation
Continue readingInterpreting the mass spectrum of an organic molecule
We can calculate the percentage abundances for each of the isotopes in an element if we know the mass number
Continue readingHow to calculate the relative abundance of an isotope
We know that relative atomic mass (Ar) is the average of (% abundance of an isotope x isotopic mass) for
Continue readingHow to calculate the relative atomic mass of an element from a mass spectrum
A mass spectrometer is able to very accurately determine the relative atomic mass of an element, by measuring the mass
The standard electrode potential for a half cell means exactly that – everything happening under standard conditions (298K, 100 kPa,
Continue readingUsing the Nernst equation to calculate the electrode potential of a half cell
We came across electrolysis of molten metal salts and of solutions at GCSE, and the good news is, nothing has
Fuel cells commonly use the reaction between hydrogen and oxygen to produce a voltage, with water being the only waste
