CopperLocation on the Periodic Table
The transition elements are located in groups 3 to 12 of the periodic table.
Properties
Because they possess the properties of metals, the transition elements are also known as the transition metals. The transition elements have low ionization energies. They exhibit a wide range of oxidation states or positively charged forms. The positive oxidation states allow transition elements to form many different ionic and partially ionic compounds. Thus, the complexes form characteristic colored solutions and compounds. Complexation reactions sometimes enhance the relatively low solubility of some compounds.
Summary of Common Properties
- Low ionization energies
- Positive oxidation states
- Very hard
- High melting points
- High boiling points
- High electrical conductivity
- Malleable
- Five d orbitals become more filled, from left to right on periodic table
