The 30 pages that link to Dmitri Mendeleev, each with the reason it gives.

• Periodic tableRelated: His table left gaps and predicted properties of elements not yet discovered.

• Atomic numberRelated: His table exposed the ordering problem that atomic number later resolved.

• Saint PetersburgRelated: He studied and worked in Saint Petersburg, where his scientific career took shape.

• Extended periodic tableRelated: His willingness to leave gaps established a precedent for placing elements before discovery.

• Periodic lawRelated: His 1869 table made periodic recurrence a powerful predictive principle.

• Alexander BlokRelated: Blok spent part of his childhood at the family estate of Mendeleev, his future father-in-law.

• Jöns Jacob BerzeliusRelated: Mendeleev’s element classification extended the organizing work enabled by reliable atomic weights.

• Periodic table extensionRelated: His successful predictions established the precedent for using periodic order to anticipate unknown elements.

• GermaniumRelated: Mendeleev predicted an undiscovered element with properties later matched by germanium.

• Henry MoseleyRelated: Moseley’s atomic-number sequence validated the periodic pattern Mendeleev had recognized.

• GalliumRelated: Mendeleev predicted an element below aluminum whose properties closely matched gallium.

• ChemistryRelated: His periodic table organized chemical properties and predicted elements not yet discovered.

• ScandiumRelated: Mendeleev predicted an element later identified as scandium, calling it eka-boron.

• TechnetiumRelated: His periodic system anticipated an element between molybdenum and ruthenium.

• Saint Petersburg State UniversityRelated: He studied and taught at the university, where he developed his influential chemical work.

• Actinide conceptRelated: His periodic framework predates the actinide concept and could not anticipate the transuranium series.

• Paul Émile Lecoq de BoisbaudranRelated: Mendeleev recognized gallium as a striking confirmation of his predicted element, eka-aluminium.

• Stanislao CannizzaroRelated: Reliable atomic weights supported Mendeleev’s ordering and comparison of elements.

• Amedeo AvogadroRelated: Reliable atomic weights, supported by molecular theory, later strengthened periodic classification.

• Main-group elementRelated: His periodic classification established the recurring patterns later used to distinguish element families.

• Per Teodor CleveRelated: Cleve’s element identifications contributed evidence relevant to periodic classification.

• History of the periodic tableRelated: His table's successful predictions made periodic classification a powerful scientific framework.

• Marguerite PereyRelated: His table left a predicted place for the element Perey later identified.

• UnbipentiumRelated: His predictions established the tradition of reserving places for elements not yet observed.

• UnhexoctiumRelated: His predictions helped establish the idea that gaps in the periodic table could signal unknown elements.

• Period 1 elementRelated: His table established the periodic framework in which the first row is understood.

• Sergey Prokudin-GorskyRelated: Prokudin-Gorsky studied chemistry in an intellectual world shaped by Mendeleev's generation.

• UnoctquadiumRelated: His use of placeholder names for predicted elements anticipated later systematic naming practices.

• UnquadbiumRelated: His predictions established the precedent of leaving systematic places for elements not yet known.

• UnsepttriumRelated: His predictions helped establish the idea that the periodic table could extend beyond known elements.
