The charge on chromium in the complex Cr(NH)Br is 3.
there is no element with the symbol R, so perhaps it is meant to read CrCl6 which is Chromium Chloride. Hope this helps! for more info on Chromium Chloride visit http://en.wikipedia.org/wiki/Chromium(III)_chloride
The compound is Chromium(III) Oxide. Chromium is 3+, since the compound has to have a charge equal to 0. Since there is 2 chromium atoms each chromium atom must have a charge of 3+ to balance out the 3(2-) charges of each oxygen atom; 2x+3(-2)=0, transpose for x(chromium), (in case you need the working out).
IONIC, because chromium is a metal and chlorine is a non-metal.
The CrN cation is typically a chromium(III) cation, where chromium has a +3 oxidation state. This means that chromium has lost three electrons and has a charge of +3.
The correct formula for the ionic compound chromium chloride is CrCl3. This is because chromium (Cr) has a 3+ charge, and chloride (Cl) has a 1- charge, so three chloride ions are needed to balance the charge of one chromium ion.

Urea acts as a ligand in the synthesis of chromium acetylacetonate (acac) complex by coordinating to the chromium ion. It helps to stabilize the complex by forming bonds with the chromium center, thereby influencing the geometry and properties of the resulting complex. Urea also assists in controlling the reaction conditions and promoting the formation of the desired chromium acac complex.

The correct formula for the ionic compound formed between chromium and chloride is CrCl3. This is because chromium has a 3+ charge and chloride has a 1- charge, so it takes three chloride ions to balance the charge of one chromium ion.

CrCl2
Chromium oxide is the light green inorganic compound coCr203. When dissolved in acid, it produces the hydrated chromium ions [Cr(H2O)6]3+.
The chemical formula for chromium(III) phosphide is CrP. In this compound, chromium has a +3 charge, while phosphorus has a -3 charge.
it is a chromium 2 as a good point of reference, and if you don't know the specific charge of an atom, check the ion to which it is bound: the phosphide ion is most commonly charged as a 3- ion because its period is has 3 electrons more than it needs to form a complete octet 2 phosphide ions (per your empirical formula) would have a total ionic charge of 6- if you distribute the (6-) charge evenly through the 3 chromium ions in your empirical formula, then each chromium ion would have to have a charge of 2+ in order for the ionic salt to be neutrally charged. therefore the chromium is chromium (II)
Any particle with 24 protons, despite the number of neutrons or the charge, is chromium.
