13. The periodic table—the transition metals

13.2.1 - List the characteristic properties of transition elements A variable oxidation number Higher melting points, harder and denser than group 1 and 2 metals Form complex ions Majority of their compounds are coloured Can act as catalysts No significant change in...

Explain the physical states (under standards conditions) and electrical conductivity (in the molten state) of the chlorides and oxides of the elements in period 3 in terms of their bonding and structure Summary of Chlorides Summary of Oxides 13.1.2 - Describe the...
