Assessment Objectives

Detailed Breakdown: Electron Configuration

• State the full and condensed electron configurations for elements and their ions, including transition metal exceptions ($Cr$ and $Cu$).
• Define isotopes and relative atomic mass ($A_r$).
• Explain why the first ionization energy of Neon is higher than that of Fluorine using nuclear charge considerations.
• Deduce the number of subatomic particles in specific isotopes and ions.
• Relate the energy of a photon to its frequency and wavelength using $E = hf$.
• Describe the emission spectrum of Hydrogen and identify electronic transitions to $n=1, 2, \text{ and } 3$.
• Calculate the weighted average atomic mass of an element from its mass spectrum peaks.
• Predict the Successive Ionization Energies pattern for a given element and justify its group assignment.
