I think the question in this quiz is referring to total mass but is hydrogen more abundant in the human body in terms of number of atoms? I assume that the large majority of the oxygen atoms are due to the high water content and each water molecule will have twice that number of hydrogen atoms...
Most common to me would be a count, not by mass unless its specified in the question. "Because of water content, the human body contains more oxygen by mass than any other element, but more hydrogen by atom-fraction than any element." https://en.wikipedia.org/wiki/Composition_of_the_human_body
@Jpcol, moles is the same thing as number of atoms (actually the number of atoms divided by 6.02 x 10^23). In moles the current answer is wrong. @someone, did you just assume that @jp knew what he/she was talking about just because they sounded like they did? If anyone wanted to know they could look it up.
Yeah, I was going to post something similar for a number of questions--lots of valuable metals and poisonous metalloids, etc.--but I got all of the suspect questions right on the first guess, and their overall guess rates are high, so I suppose the questions are fine.
There are lots of poisonous metalloid elements, too, aren't there? Maybe most of the ones I was thinking of aren't technically metalloid... or maybe they're not "extremely" poisonous.
With sign, I thought of something flat made out of metal. If it was phrased differently I would have gotten it.
And for the watch hand I tried uranium and plutonium, but radium didnt come to the surface. The rest I got though. Nice quiz (though some are slightly to simple, like germany germanium. Even if you didnt know you could guess it. Like moscovium. you could have done darmstadtium as a city. Or scandium, less obvious than some other ones)
Great quiz! Might you consider making a different clue for the atomic number question? Its just not so much fun as the others. would love to see more quizzes like this.
Oxygen is not the most common element in the human body, and you can’t change my mind. You could say that oxygen accounts for more mass in a human body than any other element, but no way is it the most common. Hydrogen is more common by far
I like this quiz, but a lot of the clues are vague enough to cause confusion, and could be worded more clearly, IMO.
"Used in Thermometers" could be nearly anything. Optical thermometers use silicon, thermocouples use any two metals, liquid thermometers can use virtually any liquid. I recommend "Used to make the first practical thermometers" to hint at the expected answer.
"Found in milk" - the best answer for this ought to be hydrogen, since that's the element with the largest number of atoms in milk. To hint at what you are going for, maybe try "Nutrient advertised by dairy corporations to be found in their products."
"Smells like rotten eggs" - pretty easy to figure out what you were thinking after the previous hints, but this element actually doesn't smell like anything unless it forms compounds with other elements.
"Malleable ductile and valuable" is too open ended. Nearly any precious metal works to answer this, so I'd recommend "Malleable ductile valuable and yellow."
"Nutrient found in bananas" is likewise open ended. Could you think of something more specific?
"Used in a once-popular type of advertising sign" is pretty easy to guess, but could also be sodium, tungsten, or several other things. Maybe say "Noble gas once used in popular advertising sings."
"Extremely poisonous metalloid" isn't even quite right. Polonium is the obvious answer, with an LD50 of 18 ng/kg. The answer marked as correct is 1 million times less poisonous than that. For reference, boron is about 50 less lethal than the answer given. Maybe hint "Metalloid used in commercial rat poison."
"Pipes made of this are being replaced" is another vague one. Replaced why? Copper pipes are being replaced for economic reasons. Maybe hint "Pipes made of this are being replaced in Flint, Michigan" or similar.
"Along with chlorine, it makes salt" - maybe
Along with chlorine, it makes table salt." To a chemist, any metal with chlorine makes salt.
"Most common element in the human body" is wrong. The correct answer is hydrogen. Maybe you meant "Element that comprises the most weight in the human body?"
It's just more satisfying if you don't have to fumble around guessing what the person who wrote the quiz was thinking. If the QM and author don't want to implement any of these suggestions, that's fine.
I agree with you, taking the questions individually, and had the same reaction.
The quiz is a little more fun if you consider it a little like a matching puzzle where you are finding the best answers (not necessary "correct") and not reusing them. Then it becomes a little more clear what's being asked for, since you can only answer "copper" (another element known for its value, ductility and malleability) for pennies, leaving gold to answer for malleability and value.
The quiz is structured with purposefully terse "hints" at "guesses" rather than "definitive answers to clear questions", it's just the style of the quiz. I do think "Most common element in the human body" should be rephrased as "Greatest proportion of human body" since "common" unambiguously refers to frequency, i.e., a count, and you don't need to say you're looking for an element, since that's the quiz.
Europeans first become aware of Argentina when it was visited by John Cabot (who was Venetian). His son Sebastian Cabot started colonizing it not long after. Argento is Venetian for silver, and the -ina ending is diminutive, so Argentina in Venetian is like "Silver-ette". The Cabots had close ties to both England and Spain, and a home in Seville, which is why Cabot's North American expedition yielded colonies for England and Cabot's South American expedition yielded colonies for Spain (those were two of the richest European nations at the time. Italy didn't exist, and Venice was a small kingdom, not a large empire looking to conquer the world.).
Also, in Spanish, Rio de la Plata means River of Silver. Incidentally, it's the same origin in naming as Argentina, just in Spanish rather than Venetian.
I don't think the question is in-salvageable, but I do think it should probably be reworded; possibly along the lines of what you suggest.

Uranium's needy ex-girlfriend?

It's symbol comes from the Latin word Argentum which means silver or silvery
There is no relation to Argentina as far as I can see
Good quiz though 9/10
