Learning Goals:

Understand that atoms can be modelled as a nucleus surrounded by electrons in distinct energy levels held together by electrostatic forces of attraction between the nucleus and electrons
 
Understand location of electrons within atoms can be represented using electron configurations;
 
Understand the structure of the periodic table is based on the electronic configuration of atoms
 
Use and Apply the nuclear symbol notation M𝑍𝑍𝐴𝐴 to determine the number of protons, neutrons and electrons in atoms, ions and isotopes
 
Recall the relative energies of the s, p and d orbitals in energy levels to construct electron configurations for atoms and ions up to Z = 36 and recognise that the periodic table is arranged into four blocks associated with the four sub-levels — s, p, d and f
 
Apply the Aufbau principle, Hund’s rule and the Pauli exclusion principle to write electron configurations for atoms and ions up to Z = 36 and use orbital diagrams to represent the character and relative energy of orbitals
 
Recognise the electron configuration of Cr and Cu as exceptions
