Definition 2, revision 1 · Jul 26, 2026, 11:18 AM UTC
Compared with Definition 1, revision 1, the source of this proposal.
The Removed: energy released or required whAdded: difference in total energy between a compound Removed: forms fromAdded: and its constituent elementsRemoved: , used to judge whether a predicted structure is thermodynamically favorableAdded: in their respective standard states, typically expressed in electronvolts (eV) per atom or per formula unit. A negative formation energy indicates thermodynamic stability relative to the precursors. Because values may be reported using different normalization bases, datasets are not directly comparable unless the energy basis is explicitly stated.
The magnitude runs from 0 for unchanged text to 1 for complete replacement. It measures definition wording only—not authorship, quality, or community impact.
Select two current candidates to see their exact wording differences. Removed text belongs to the first selection; added text belongs to the second.
