maybe it was a typo because i thought it meant harmful, well it was when i was in school anyway
maybe they meant the n to be a h

I think X is supposed to represent the symbol for the atom e.g. C for carbon and n is the number of protons, but this is just a guess

yea lots of people put harmful as they thought could have been spelling mistake n instead of h but we have had exams before with mistakes and they always read it out at begining

hmm maybe they didnt notice its probably worth asking your teacher
i have lookd on loads of gcse revision sites and it hasnt appeared
and if they have put it in a paper without dding it in revision books etc then they have made a boob
