The graph shows a sketch of log 10 ionisation energy against number of electrons removed for magnesium.

Question:

The graph shows a sketch of log₁₀ ionisation energy against number of electrons removed for magnesium. Use this sketch graph to answer the following questions.

a. Explain why the first two electrons are relatively easy to remove.

b. Why is there a sharp rise in ionisation energy when the third electron is removed?

c. What information does the graph give about the electron arrangement of magnesium?

d. Give the equation for the ionisation energy marked x (the 5th ionisation energy).
