CHAPTER 3: Electrons in Atoms
- Sub-shells and Atomic Orbitals
- Electronic Configuration
- Ionisation Energy
Learning outcomes:
- 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
- describe the shapes of s and p
- state the electronic configuration of atoms and ions given the proton number (and charge), using the convention 1s²2s²2p⁶
- (i) explain and use the term ionisation
- explain the factors influencing the ionisation energies of
- explain the trends in ionisation energies across a Period and down a Group of the Periodic
- deduce the electronic configurations of elements from successive ionisation energy
- interpret successive ionisation energy data of an element in terms of the position of that element within the Periodic
