molybd- +

(Greek > Modern Latin: lead [the metal])

A ferroalloy (iron) containing up to 60 percent molybdenum.
A salt of molybdic acid (compounds in which the element has a higher valence or a number that reflects an element's ability to combine with other elements).
molybdate orange, molybdate chrome orange, molybdenum orange
A fine orange powder that is a solid solution of lead molybdate, lead chromate, and lead sulfate; used as a pigment in paints, inks, and plastics.
A metallic, lead-gray hexagonal mineral with a perfect cleavage, trimorphous with jordisite and molybdenite-3R, having a specific gravity of 4.62 to 5.06 and a hardness of one to 1.5 on the Mohs scale.

A mineral occurring in soft, lead-gray, foliated masses or scales (characterised by being separable into thin plates or folia; as, graphite has a foliated structure), resembling graphite.

1. Referring to molybden, or obtained from it.
2. Containing, molybdenum; specifically, designating those compounds in which molybdenum has a lower valence as contrasted with molybdic compounds.
1. A polyvalent metallic element that resembles chromium and tungsten in its properties; used to strengthen and harden steel.
2. A heavy metallic element having the symbol Mo, the atomic number 42, an atomic weight of 95.94, a melting point of 2617 degrees Celsius, and a boiling point of 5560 degrees Celsius; highly conductive and resistant to heat; used in high-temperature alloys, resistors, and audio magnets.

From an earlier word for lead; because of its resemblance to lead.
