Relative atomic mass and relative molecular mass. Relative atomic mass and relative molecular mass in of 12C. Relative formula mass. Calculate relative atomic mass from isotopic abundance, limited to mononuclear ions. Look at mass spectra of compounds to determine the relative formula mass. 3.1.1.3 Electron configuration. Electron configurations of atoms and ions up to Z = 36 in terms of shells and sub-shells (orbitals) s, p and d. Ionisation energies (IEs). 3.2.1.1 Classification. An element is classified as s, p, d or f block according to its position in the Periodic Table, which is determined by its proton number. 1.2 weeks Give electron configurations in terms of shells and sub-shells for atoms and ions up to Z=36 Define first ionisation energy. Write equations for first and successive ionisation energies. Explain how first and successive ionisation energies in Period 3 and in Group 2 give evidence for electron configuration in sub-shells and in shells. Students: Write electron configurations for atoms and ions up to Z=36 in terms of shells and sub-shells. Find out about the historical development of the Periodic Table. Plot graphs of both first IE and successive IEs and use them to identify and explain the trends. Use successive IE data to determine group an element is in.
