I correctly named and placed all elements with the following exceptions:

I transposed the three pairs: Rubidium/Strontium, Hafnium/Tantalum, and Copernicium/Roentgenium. I correctly gave the symbols for all of the above except Copernicium (Cn), again just the transposition. No credit.

I also goofed the spelling of Platinum by adding an extra i, a la the British spelling for Aluminium. No credit.

I correctly identified the rows (periods) and columns (groups) of the table by same names, I just didn't pluralize them like I had it in my key. +2 credit.

Among types of elements, I incorreclty referred to polyatomic and diatomic nonmetals as being "ions". I did correclty identify post-transition metals there was just a spelling flub relative to my key, again. +1 credit.

Otherwise I goofed the symbols for Seaborgium and Antimony (transposing these two), Darmstadtium, Tennessine (Ts), Protactinium, and Thulium. No credit.
