Is molybdenum a cation?
3.1. The molybdenum atom is described in its ground state by an electron configuration [Kr] 4d5 5 s1. As a consequence, molybdenum cations Mop + for 4 ≤ p ≤ 6 are characterized by configurations [Kr] 4d6 − p with a partially filled (p < 6) or an empty (p = 6) 4d shell.

Is molybdate and molybdenum same?
As nouns the difference between molybdate and molybdenum is that molybdate is (chemistry) the anion moo42− while molybdenum is a metallic chemical element (symbol mo) with an atomic number of 42.
What is the charge of Mo?
Molybdenum has several oxidation states, the most stable being +4 and +6 (bolded in the table at left).
How many electrons are present in the MO 4 ion?
According to Bohr’s formula, the fourth shell will have twelve electrons but the fourth shell of molybdenum will have thirteen electrons and the remaining one electron will be in the fifth shell. Therefore, the order of the number of electrons in each shell of the molybdenum(Mo) atom is 2, 8, 18, 13, 1.
What is the charge of molybdenum?
What is molybdate ion?
Molybdates are compounds containing negatively charged oxymolybdenum ions. For the most part, mineralogically, the simple tetraoxomolybdate(VI), or molybdate ion, MoO42 −, is present. Under acid conditions, molybdate ions polymerize and this process can incorporate other chemical entities.
What is the oxidation state of Mo?
Molybdenum exhibits oxidation states of +2 to +6 and is considered to display the zero oxidation state in the carbonyl Mo(CO)6….molybdenum.

What is a molybdate ion?
3D model of the molybdate ion. In chemistry a molybdate is a compound containing an oxoanion with molybdenum in its highest oxidation state of 6.
Does molybdate adsorption depend on ionic strength?
Molybdate adsorption was lowest for the highest solution ionic strength. Ionic strength dependence of molybdate adsorption was slight on goethite, montmorillonite, and soils, suggesting an inner-sphere adsorption mechanism.
How are molybdates used in catalysis?
Molybdates are widely used in catalysis. In terms of scale, the largest consumer of molybdate is as a precursor to catalysts for hydrodesulfurization, the process by which sulfur is removed from petroleum. Bismuth molybdates, nominally of the composition Bi 9 PMo 12 O 52, catalyzes ammoxidation of propylene to acrylonitrile.
Can molybdate be used as a corrosion inhibitor?
However, molybdate requires high concentrations when used alone, therefore complementary corrosion inhibitors are generally added, and is mainly used in high temperature closed-loop cooling circuits.
