The correct formula for Chromium (II) Carbide is Cr2C.
This is because Carbon (or Carbide) has a negative 4 charge because it wants to gain four electrons to have it's valence electrons to equal 8. So if it gains four electrons, and electrons are negatively charged, then it has a negative four charge. Chromium has a positive two charge because it has the roman numeral II next to it. Chromium is a metal and all metals are positively charged when they become ions, so it has a positive two charge. In order to be a stable compound, the charges must cancel each other out. So in order for that to happen, you must have two Chromium atoms, to make a positive four charge in total, and one Carbon, to make a total of negative four. And since positive four and negative four cancel each other out, then the formula is Cr2C (two Chromium and one Carbon atom).
The formula of Chromium (II) oxide is CrO.
the chemical formula for chromim(II) fluoride is CrF2
Iron (II) Carbonate
The formula CrI2 represents chromium (II) iodide, which is a chemical compound composed of chromium and iodine ions in a 1:2 ratio.
Annon:The chemical formula of chromium II sulfate is CrSO4.Miki-San-X: ActuallySince this is probably Ionic naming since it starts with a metal and ends with a non metal you would take chromium (II) Sulfate and cross them-Like so-Start:Cr(II) SO4 (-2)We know that sulfate is SO4 with a -2 superscript and that chromium is a transition metal, but that it has a positive charge to counteract the negative charge of the -2.You will drop the charge and cross them-Cr2(SO4)2since you brought the -2 from the sulfate down to the chromium it becomes positive 2 because you dropped the charge before crossing. The reason you put the (SO4) in parenthesis is because you cannot, in a problem like this, have 42 next to your polyatomic ion. You have TWO of that ion, NOT 42.Hope I helped

Cr2O3 is the chemical formula for chromium (III) oxide
The formula CrI2 represents chromium (II) iodide, which is a chemical compound composed of chromium and iodine ions in a 1:2 ratio.
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>
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.
The chemical formula for chromium(II) bicarbonate is Cr(HCO3)2.
The formula is CrN. It is called Chromium nitride and Chromium(III) nitride. Chromium also forms second interstitial nitride, dichromium nitride - Cr2N
Chromium (II) Carbonate. Although I'm not sure Chromium (II) can form, there might be an overall charge on your formula there...
CrO is the formula for chromium(II) oxide. Cr is the elemental symbol for chrome, and O represents oxygen. The molecular weight of CrO is 68.00 grams/per mole using two significant figures. Variants of CrO include II, III and VI.
An example is the chromium chloride: CrCl2.
