Question 3 of 10

3

Fill the blank spaces to complete the text.

Ionisation of an atom is the process in which the subatomic particle, the , is removed. The outermost particle will have the binding energy, and so will be most to remove. As the particles are taken away, the energy increases, increasing the amount of energy required.
