lonisation number
(i) Estimate the lionisation energy and the 19ty ionisation energy of potassium. Use data
from the graph and your calculator.
(ii) Write the equation for the first ionisation energy of potassium.
(iii) Explain why there is a general rise in the value of the successive ionization energies.
(iv) Explain each of the three sharp rises in the graph. You should include details of the
subshell from which the electron is removed at each sharp rise.
