| This is a really good quiz. As an astrophysicist, I got most of the answers, but some like zirconium make no sense to me at all! If anyone wants an explanation of why these elements are abundant:
The big bang made mostly hydrogen, and helium and almost nothing else.
Small stars make more helium.
Late in their lifetime, bigger stars fuse helium into heavier elements eg helium + neon gives magnesium, magnesium + helium = silicon etc, so elements with even proton number tend to form.
Nuclear binding energy peaks at iron, so elements beyond iron are very rare (only produced in supernovae).
Everything else is really rare, apart from nitrogen, which is formed in a process called the CNO cycle (Wikipedia it, its got a very clear diagram) |
