“The metals at preſent amount to 21 ; only 11 of which were known before the year 1730. Their names are gold, ſilver, platinum, mercury, copper, iron ⟳, tin, lead ⟳, zinc, antimony, biſmuth, arſenic, cobalt, nickel, manganeſe, tungſten, molybdenum, uranium, tellurium, titanium, chromum.”

“Technical terms like ⟳ ferrite, perlite, graphite, and hardenite were bandied to and fro, and when Paget glibly brought out such a rare exotic as ferro-molybdenum, Benson forgot that he was a master ship-builder, […]”

“Extensive deposits of copper and molybdenum ore, situated some 200 miles northwest of Ulan Bator between the Selenga and Orkhon Rivers, will eventually be extracted by open ⟳‐pit methods and processed at the still unfinished town of Erdenet.”

“At pH levels below 5, wheat yields may be low, molybdenum may become ⟳ unavailable to plants, and other trace elements may be concentrated to toxic levels.”

“a quadruple bond between molybdenums”

“Thus in M₄O₁₁, for example, ¾ of the molybdenums are octahedrally connected and ¼ are tetrahedrally coordinated and, furthermore, the formula is compatible with the existence of one Mo(IV) for every three Mo(VI), so at first glance ⟳ the compound might appear ⟳ to be a class I mixed valence system.”
