Atomic Structure structured questions · GCE A-Level H1 Chemistry

Learning objectives

• identify and describe protons, neutrons and electrons in terms of their relative charges and relative masses
• deduce the behaviour of beams of protons, neutrons and electrons in an electric field
• describe the distribution of mass and charges within an atom
• deduce the numbers of protons, neutrons and electrons present in both atoms and ions given proton and nucleon numbers (and charge)
• — describe the contribution of protons and neutrons to atomic nuclei in terms of proton number and nucleon number
• — distinguish between isotopes on the basis of different numbers of neutrons present
• describe the number and relative energies of the s, p and d orbitals for the principal quantum numbers 1, 2 and 3 and also the 4s and 4p orbitals
• describe the shapes of s and p orbitals [knowledge of wave functions is not required]
• state the electronic configuration of atoms and ions given the proton number (and charge)
• explain the factors influencing the ionisation energies of elements (see the Data Booklet) (see also Section 4)
• deduce the electronic configurations of elements from successive ionisation energy data
• interpret successive ionisation energy data of an element in terms of the position of that element within the Periodic Table
