Formulas of Impossible Ions

Here are the formulas of the impossible ions you mentioned:

- Br- (Bromide ion) - This is a possible ion. It is the anion of bromine, which has a charge of -1. Bromide ions are commonly found in salts and compounds. - Al3+ (Aluminum ion) - This is a possible ion. It is the cation of aluminum, which has a charge of +3. Aluminum ions are commonly found in various compounds and minerals. - Ca3+ (Calcium ion) - This is an incorrect notation. The charge of a calcium ion is +2, not +3. The correct notation for the calcium ion is Ca2+. - I- (Iodide ion) - This is a possible ion. It is the anion of iodine, which has a charge of -1. Iodide ions are commonly found in salts and compounds. - N2+ (Nitrogen ion) - This is an incorrect notation. Nitrogen typically forms covalent bonds and does not commonly exist as a cation. The correct notation for the nitrogen ion with a positive charge would be N+. - SO42- (Sulfate ion) - This is a possible ion. It is the anion of sulfate, which has a charge of -2. Sulfate ions are commonly found in salts and compounds.
