  1. 1How many electrons in Ca(2+)?
    1. A2
    2. B22
    3. C18
    4. D8
    5. E20
  2. 2Electrons can only orbit nuclei in fixed orbits with specific characteristic energy levels.
    1. AVerdadero
    2. BFalso
  3. 3Ionisation of an atom is the process in which the subatomic particle, the [blank_start]electron[blank_end], is removed. The outermost particle will have the [blank_start]least[blank_end] binding energy, and so will be most [blank_start]easy[blank_end] to remove. As the particles are taken away, the energy increases, increasing the amount of energy required.
    1. Aelectron
