Slide 2 of 12
Learning objectives
Concepts:
–Aufbau principle, Pauli exclusion principle, Hund’s rule, orbital, s orbital, p orbital, d orbital, f orbital,
–electron configuration, valence electron, core electron, inert gas configuration, condensed, condensed with inert gas notation, half-shell stability, full-shell stability, monatomic ion electron configuration
–Electron (orbital) in box diagram, unpaired electron, free radical
Skills:
–Provide a ground state electron configuration of the type desired for an atom or a monatomic ion up to Z = 56 using s, p, d, f notation
–Determine the number of valence and core electrons for an atom or a monatomic ion
–State the rules governing the order in which orbitals are filled
–Relate the electron configuration of an atom to its position in the periodic table
