1. Sulfur Ion Charge
2. Carbon Ion Charge

Negative charge. Does not retain Attracts and retains cations. Figure 1: Substitution of silica by aluminum in soil clay particles causes clays to have a negative charge. Because of this negative charge, the soil can hold on to positively charged cations such as calcium (Ca 2+), magnesium (Mg ) and potassium (K+). The Fe has to cancel out the charge of the -2. You then have to look at your periodic table and see if one of iron's oxidation states is a +2. The iron is the cation and the hydroxide ion is the anion. Cr(OH)3-Same as the FE(NO3)2, the polyatomic OH is hydroxide. It has a charge of -1, there are three of them so all together is it a charge of -3. I know that the charge of the Fe cation is 3+, but is this the correct way so find the charge of Fe? O's charge is always 2- & 2- 'times' (O)3 = -6 because the charge of an ionic compound is. Cations & Anions Cations include everything from hydrogen, with a +1 positive charge, to aluminum, with a +3 positive charge. Anions include phosphate, nitrate, and other essential elements that hold a -1 or -2 charge. Table 1 shows the most common cations and anions along with their chemical formula and charge. Give either the name or formula (with the correct charge) for each of the cations.
