In my vocabulary crossword puzzle, I have one clue answer left to fill in the puzzle, but the clue doesn't match anything that even EXISTS:
9. A group 18 element (on the periodic table)
Answer so far: N??E?????S
NONE of the group 18 elements fit in here, though. And I triple-checked my other clue answers because they were in the exact glossary for the chapter, except for this clue and a few others.
Does anyone have any idea what could go in this answer space?? Any help is GREATLY appreciated!!
Group 18 is He, Ne, Ar, Kr, Xe, Rn
With so few to choose from I suggest some of your other words may be incorrect.
