Poorly done quiz. First, the lack of variety. It's mostly chemistry, some physics, and one anatomy question.

Second, some questions are vague, and could be answered in different ways, like the sodium one (btw, it's not "under" but "in"), or the mesons. Third, bronze should be accepted for tin and copper, as it is actually more correct than "bell metal", which is a type of bronze. And positron should be accepted for the radioactive element question.

Finally, accepting numbers in the bone question and not in the colours one (btw, it's just light, not sunlight; that would imply light from sources other than the sun could have a different amount of colors).
