A Level Chemistry Question

Hi, I was wondering if anyone could explain this working out for the q ? 😂😂 i.e how do we know which boxes we’re ticking or crossing

Hi there.

Maybe write underneath the blank boxes for the corresponding ionisation energy the electrons i.e. 1s1, 1s2, 2s1, 2s2, 2p1, 2p2, 2p3 etc. to help prevent confusion when trying to work it out. The question itself is quite wordy but only worth one mark so don't worry too much about this.

Hope this helps. :smile:
Good luck for the exams.
