Woo! Finished! Rg was a pain. Message me for hints if you like
I know the symbols in Copper but I don't know how to list them. When I simply keyed them in, it states it's the wrong answer. Could help me with the format of the answer?
does anyone have hints for gold?

Just type in the symbols! I put them in order of increasing atomic weight. If that isn't marked correct then you've got the symbols wrong
Silver anyone

Rubbish isn't it. I thought I solved it within about 15mins and haven't really thought of anything particularly different since then....
FINALLY did it. I had to guess a bit in the end!
Spoiler
Did it! If anyone needs help feel free to message me
Argh! Gold! 😤
