A recent paper introduced the term \u201chydridic hydrogen bond\u201d to describe interactions where hydrogen atoms bound to electropositive elements (e.g., Si, Ge, Sn) act as electron donors. However, such terminology conflicts with IUPAC definition, which requires hydrogen to be bonded to more electronegative atoms for a hydrogen bond (HB). Herein, we combine electrostatic potential analysis, energy decomposition, ELF\/QTAIM, and NBO calculations to show that interactions involving hydridic hydrogen atoms as donors and heavier main group elements (Br, Se, As) as acceptors are better classified as halogen, chalcogen, and pnictogen bonds (PnBs), respectively. Our results confirm the nucleophilic character of hydridic hydrogen atoms and the electrophilic role of the interacting elements via \u03c3\u2010 and \u03c0\u2010hole interactions, consistent with established IUPAC definitions. Experimental evidence from NMR supports this classification. By clarifying these interactions\u2019 nature and directionality, we advocate for nomenclature that aligns with chemical intuition and community standards, thereby avoiding confusion caused by unnecessary redefinitions.<\/jats:p>","DOI":"10.1002\/chem.202502074","type":"journal-article","created":{"date-parts":[[2025,8,13]],"date-time":"2025-08-13T11:45:25Z","timestamp":1755085525000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Naming Matters: Hydridic Hydrogen Atoms are Halogen, Chalcogen, and Pnictogen Bond Acceptors not \u201cHydridic Hydrogen Bond\u201d Donors"],"prefix":"10.1002","volume":"31","author":[{"given":"Rosa M.","family":"Gomila","sequence":"first","affiliation":[{"name":"Department of Chemistry Universitat de les Illes Balears  Crta de Valldemossa km 7.5 Palma de Mallorca Baleares 07122 Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberta","family":"Beccaria","sequence":"additional","affiliation":[{"name":"NFMLab, Dept.
