What is a complex ion?
d-block metal cations readily form complexes with ligands – neutral molecules such as water or anions such as the chloride

Writing the electron configuration for a transition metal
The transition metals are d-block elements (Groups 3-12 of the Periodic Table) whose atoms have a partially filled d-orbital or

Explaining the trend in atomic radius across Period 3
Before we jump straight in, we really need to define how we measure the radius of an atom … This

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

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