Wow! Great Feature. This user has less than 1000 total takes, so I'm glad they got a Feature.

If you're in the comments looking for hints (cheating), I'll give you a big hint: they're ALL metals, though I think a couple are technically classified as metalloids.

Sure they are. One of them is sometimes called a metal or metalloid depending on the classification scheme, but all exhibit metallic bonding and are broadly classified as metals.

In astronomy, all but Hydrogen and Helium are metals.

This quiz has the added difficulty that in my mother tongue the set has a similar size but it doesn't overlap that much with the English one.

I found Tungsten misleading, cause it's also called Wolfram.

Of course I get 8/10 no problem, then go completely blank and watch as 'Gold' and 'Silver' pop up in the answers - Woops!

Copper Cu is also confusing as it doesn’t have a U.

But "C" is the same as Copper's first letter.

Good quiz and similar to a couple of quizzes I created previously which show the reasons for the choice of symbol for these elements, see Elements with 'irregular' Symbols and Elements that differ from their symbols.
