Ionization energy is the quantity of energy that an isolated, gaseous atom in the ground electronic state must absorb to discharge an electron, resulting in a cation. This energy is usually expressed in kJ/mol, or the amount of energy it takes for all the atoms in a mole to lose one electron each.
TASK 1: Start by studying the videos below.
TASK 2: Literacy and Numerical tasks. Write your answers out and submit for marking in September.
1: State the three factors that determine the magnitude of the first ionisation energy of an element.
2. write equations to represent the first ionisation energy of sodium, the second ionisation of calcium and the fourth ionisation energy of carbon.
3. Draw a sketch graph for the successive ionisation energies of phosphorus.
4. Research and explain the trend in ionisation energies as you down a group and across a period.
