Structure 3.1 The periodic table: Classification of elements (HL)
Structure 3.1.7
Understandings:
  • Discontinuities occur in the trend of increasing first ionisation energy across a period.
Learning outcomes:
  • Explain how these discontinuities provide evidence for the existence of energy sublevels.
Additional notes:
  • Explanations should be based on the energy of the electron removed, rather than on the “special stability” of filled and half-filled sublevels.
Picture
This video covers the discontinuities of first ionisation energy across a period. 

Structure 3.1.8
Understandings:
  • Transition elements have incomplete d-sublevels that give them characteristic properties.
Learning outcomes:
  • Recognize properties, including: variable oxidation state, high melting points, magnetic properties, catalytic properties, formation of coloured compounds and formation of complex ions with ligands.
Additional notes:
  • Knowledge of different types of magnetism will not be assessed.
Linking questions:
  • Structure 2.3 What are the arguments for and against including scandium as a transition element?
Picture
This video covers the transition elements.
Picture
This video covers the magnetic properties of the transition elements. 
Picture
This video covers the structure and bonding of complex ions. ​
Picture
This video covers ligands. ​
Picture
This video covers how to deduce the charge and oxidation state of a central metal ion. ​

Structure 3.1.9
Understandings:
  • The formation of variable oxidation states in transition elements can be explained by the fact that their successive ionisation energies are close in value. 
Learning outcomes:
  • Deduce the electron configurations of ions of the first-row transition elements.
Picture
This video covers the variable oxidation states of the transition elements. 

Structure 3.1.10
Understandings:
  • Transition element complexes are coloured due to the absorption of light when an electron is promoted between the orbitals in the split d-sublevels. The colour absorbed is complementary to the colour observed.
Learning outcomes:
  • Apply the colour wheel to deduce the wavelengths and frequencies of light absorbed and/or observed.
  • The colour wheel and the equation c = λf are given in the data booklet.
Additional notes:
  • Students are not expected to know the different splitting patterns and their relation to the coordination number.
Linking questions:
  • Reactivity 3.4 What is the nature of the reaction between transition element ions and ligands in forming complex ions?
Picture
This video covers colour of complex ions. ​
