WebRoman numeral notation indicates charge of ion when element commonly forms more than one ion. For example, iron(II) has a 2+ charge; iron(III) a 3+ charge. Anions 1- acetate C 2H 3O 2-cyanide CN- amide NH 2-cyanate OCN-hydrogen carbonate fluoride F- (bicarbonate) HCO 3-hydride H- hydrogen sulfate hydroxide OH-(bisulfate) HSO 4 Web1) Fixed-charge metal ions take the full name of the element plus the word "ion." -Example: Na^+ -- sodium ion 2) Variable-charge metal ions take the full name of the element followed by a roman numeral (in parentheses) that gives the ionic charge plus the word "ion." Example: Fe^2+ = iron (II) ion Fe^3+ = ion (III) ion Cu^2+ = copper (II) ion

Chemistry Honors - Fixed-charge and Variable-charge …

WebJun 8, 2024 · The anions in these compounds have a fixed negative charge (S 2−, Se 2 − , N 3−, Cl −, and \(\ce{SO4^2-}\)), and the compounds must be neutral. Because the total number of positive charges in each compound must equal the total number of negative charges, the positive ions must be Fe 3 +, Cu 2 +, Ga 3 +, Cr 4 +, and Ti 3 +. These … WebJul 21, 2024 · By fixed charge, we mean that we can always predict the charge on the ion. An oxide ion, for example, always has a charge of -2. It is impossible for oxygen to form an ion with a -1 charge or a -3 charge. Many metals, on the other hand, form ions that have … genshin gains and losses
