Why the order they are in?

It was certainly confusing not to have them in order of the atomic number as usual.

I think it's better this way. Now you actually have to pay attention to what you're doing.

yeah, the order is goofy, this definitely wouldn't have gotten a vote for feature from me

I think this order is on purpose so you need to use the symbols to find them. I know every single element in order of atomic number but not the symbol and the symbols is whats being tested here

how do you know the atomic numbers but not the symbols though?

That's easy - easier than learning the symbols - you just start at the beginning of the periodic table and learn the order. I'd say I can easily match every element by name to its atomic number, or vice versa, but I probably couldn't 100% the symbols.

Without the atomic number order, this is more about recognizing the symbol...

was slightly bothered that they weren't in order...this order isn't completely random either; elements in the same group appear together.

There might be some merit to seeing if people can remember the first 20 elements of the periodic table... if you don't give them the symbols. With the symbols, it's just a "Periodic Tables by Symbol" quiz that, for no particular reason, limits itself to the first 20. It would seem to make way more sense to just have a random 20 elements quiz.

I'm glad there's a quiz catering to those of us who only care about the important elements.

Please accept Kalium and Natrium for their elements. Also, maybe just accept fluor for fluorine, as a non-native English speaker I know the element but not the English translation.

Thinking about it, a lot of countries do use kalium and natrium as alternative to potassium and sodium (my country included): https://preview.redd.it/kysbe884jci51.jpg?auto=webp&s=19fd6b17fb0fbcd28f8a070c1d3d60d8bb8fc043

and though obsolete, both natrium and kalium also appear in English language dictionaries (checked Merriam-Webster and Collins), so I bet there's some justification to accepting those names too.

That seems to have been fixed, because I know I typed aluminium.

I typed aluminum even though I am British. It's one letter fewer after all.

You scored 19/20 = 95%

Ah close for somone that doesn't know much about the periodic table and dman only better than ~51%
