Question
Why noble gases have the largest ionisation energy?
✓
Answer
Noble gases have the largest ionisation energy compared to any other elements in a given row as they have completely filled orbital ($ns^2np^6$) in their outer most shell. They are extremely stable and have a small tendency to gain or lose electrons. Hence noble gases have the largest ionisation energy.
