@TomHolland That's actually not always true, there are several cases due to some weird properties of elements where an element with a smaller atomic number has a higher atomic weight, e.g. Cobalt (27, 58.93) and Nickel (28, 58.69)
Spent a long time racking my brain for D and E. When I finally ran out of time and the answer was revealed I realised I probably should have given up some time ago.
The quiz should probably specify that 'lightest' refers to the lowest Atomic Number rather than density. I spent ages trying to figure out how Argon (as a gas) wasn't 'lighter' than Aluminium.
Didnt get phosphorus cause it is an f sound and in my country the word starts with an f aswell. And typed iodine, iridium, indium two or three times.. I didnt get why it didnt work and what i was missing... Iron never came to mind ( I guess that is, because at some point I tried to remember the periodic table by (element) letter, so iron wasnt in that group of i's
You thought Sodium would be under letter N, so you never tried it.

Pronounce it properly, and you will spell it properly
