1.

Draw a cross (x) on Figure 1 to show the second ionisation energy of carbon.

[1]
2.

Identify the element in Period 2, from lithium to neon, that has the highest second ionisation energy.

Give an equation, including state symbols, to show the process that occurs when the second ionisation energy of this element is measured.

If you were unable to identify the element you may use the symbol Q in your equation.
