My first attempt at a tiny Enigmatic Crossword, using the no-macro tool (which I'll upload once I have enough space).
For the unfamiliar, a Yoruichi-san Enigmatic Crossword has words (primarily English) formed exclusively of atomic symbols (e.g. H, He, Li...). That is, each cell of the crossword contains exactly one atomic symbol. There are two sets of clues--the typical crossword puzzle clues ("Word clues") and the sums of the atomic numbers ("Sum clues")
