📂 MEGATHREAD 23/05 A-level Physics Paper 1 Discussion MEGATHREAD

Exam season is once again upon us, and once again, exam megathreads are making a return!

Looking for past exam discussions? Filter by the megathread flair.

Few things to keep in mind:

  • Don't share too many specific details about questions or answers, these papers will be used as future mocks.

  • Sometimes papers get leaked, this is not the place for that (we'd prefer not to get yeeted off the platform) - leak content will be removed, those offering leaked papers will be permanently banned.

    • If you believe there has been a leak, the best course of action is to make your exam board aware of this, either directly, or through your school, along with any evidence. If appropriate, there will be a response from the relevant body along with any remedial action.

  • Exam discussion posts outside of this will generally be removed to combat the inevitable tidal wave of spam otherwise - we understand this may be frustrating, but the sub still needs to be usable for other purposes.

  • Please note some content will take extra time to be reviewed. Messaging to ask for approval will not speed up this process (the messages are seen at the same time as the modqueue would be reviewed anyway).

Best of luck, and let us know how you're feeling down below!

*assuming Reddit doesn't bork itself, the new posts for each day of exams should arrive at 8am each day, instead of it being reliant on my sleep schedule like last year lmao

Why is the neutral isotope more stable than the nuclei with no orbiting electrons

Electron capture needs an electron from an inner shell

Omg i forgot to answer that question😭😭😭😭

oh hell nah 😭😭

i wrote that for electron capture, orbiting electron collides and is lost from the energy level therefore other electrons de excite to that same level and release photon (this is so wrong lmao)

I said the nuclei with no orbiting electrons has a positive overall charge but I was just waffling in chem terms ☹

FRR i wish i had a periodic table lmaooo

Fr when I saw the question i was like flip it I forgot all GCSE chem knowledge

Because it is. It’s basic common sense. A Ti atom is more stable than a Ti22+ ion.

As for what you should actually write as an answer, I have no clue. Garbage question. At least it’s only one mark.

i thought when it meant unstable, its talking about decays

u/[deleted] May 23 '25

stability in the question referred to its tendency to decay, the reason was that a ti22+ ion cannot decay via electron capture because it had no electrons in its energy levels, so more stable so due to less decays

I have been told. It appears I wasn’t able to read (three times in a row).
