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, […]

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.

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.
