Is CrN cation a chromium II or III?
It is a chromium III
What is the symbol for the chromium(II) ion?
Cr^+2 is the symbol for the Chromium(II) ion
Is total chromium the same as chromium III?
Chromium has several valence states, only one of which is Chromium III. States 2, 3, and 6 are most common but 1, 4, and 5 are possible. Total chromium means the amount of chromium in all valence states.
Write the name of the compound Cr3 PO3 2?
Chromium (iii) Phosphite
Is Cr3P2 chromium II or III?
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)
Is CrN cation a chromium II or III?
It is a chromium III
What is the electronegativity of chromium?
Chromium has three valences: 2, 3, and 6.
What is Cr NO2 2?
chromium(II) nitrite
What is the symbol for the chromium(II) ion?
Cr^+2 is the symbol for the Chromium(II) ion
Chromium IV oxide formula?
CrO2this is the incorrect formula. For Chromium II oxide the formula is actually CrO without the 2. The reason for this is simple. the II after chromium indicates that it has a charge of +2, and the oxygen, we know is in group 16, has a charge of -2. The formula CrO2 is actually the formula for chromium IV oxide>

How many isotopes does chromium have?
Chromium has 25 known isotopes, 2 isomers, 3 of which are non-radioactive.

What is the name of the compound CrP?
Chromium Phosphide... Cr is the element Chromium and P is the element Phosphorus (It's a binary ionic compound -2 elements- so the second element ends in -ide)
What is the formula for chromium 2 bicarbonate?
Cr(HCO3)2
What is the ionic charge on the chromium ion in the ionic compound that has the formula Cr2O3?
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).
