Top-10 most frequent invalid atom types (r = 0) from select data sources. Shown are the top-10 most frequent atom types that fail the PubChem valence list for the top-3 depositors of substances containing failing atom types: a SCRIPDB, b IBM, and c ChemSpider. Atom types are ranked by their relative frequency in substances deposited by the respective contributor that have at least one atom that does not pass the valence list. Atom type incidences were calculated for each depositor separately.
