The trend in the bonding and structure of the Period 3 oxides can be explained in terms of the increasing
Atomic radius Dedicated post explaining the trend in atomic radius is right here! Melting points and structure The melting point
Before we jump straight in, we really need to define how we measure the radius of an atom … This

Group 7 consists of the elements fluorine, chorine, bromine, iodine and astatine, and they are known as the halogens. All

When we consider the elements of Group 2 we are invariably only investigating magnesium, calcium, strontium and barium. All isotopes
If we were to measure the change in concentration of a reactant over time and then plot a graph of
Catalysts are able to lower the activation enthalpy, Ea, for a reaction, increasing the number of successful collisions between reactants
