Does chromium chloride have a charge?
Chromium chloride can is either CrCl3 or CrCl6. A salt is usually uncharged since the cation (here Cr3+ or Cr6+) and the anion (Cl-) combine to neutralise the charges and form a salt. Some salts can have some covalent characteristics though, but in this case both compounds above are neutral.
The formula of chromium chloride is CrCl3 and the formula for silver chloride is AgCl. The relevant formula unit masses are 158.36 for chromium (III) chloride and 143.32 for silver chloride. The gram atomic masses of chlorine, chromium, and silver are 35.453, 51.996, and 107.866 respectively. Therefore, the mass fraction of chloride in chromium (III) chloride is [3(35.453)/158.36] or 0.671628 and the mass fraction of chloride in silver chloride is 35.453/143.32 or 0.24737. Therefore, to…
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).
Since it is an ionic compound, the charges on the Cr and the O have to balance out to 0 (zero). The charge on a oxygen atom is always 2-. Multiply that by three and you get 6-. Since the charge has to balance out, the Chromium must have a total charge of 6+. Divide by 2 to get 3. Each Chromium atom has a charge of 3+. Hope this helps!
CrO2 this 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>
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…
