Good point, an ion is a charged atom whereas, an isotope is the same element with a different number of neutrons. Maybe I should be more specific with the clue. Thank you.

Ah.. diffraction. I got stuck on diffusion.

The answer for N is used in the clue for I. Maybe one of those should be changed?

Minimum energy needed to 'free' an electron from a surface, could also be the ionisation energy

...but that doesn't start with W.

Like: "One of the four fundamental states of matter" could also be e.g.: Liquid. But that doesn't start with P, so is clearly not the answer being sought.

Same thing with W.

I reckon you could make the S question a bit easier, nominated though, we need more science quizzes

Could be a fair comment, although I felt the mention of a cat might be too easy. Maybe something in between?
