What is the charge of ions in the carbon family?
Generally, +/- 4, rarely +/- 2.
The charge on the Sc ions in Sc2O3 is 3+. This can be determined by recognizing that oxide ions always have a charge of 2-, and there are three of them, so the total oxide charge is 6-. There are two scandium ions, and since the compound must be neutral, the total charge on the two scandium ions has to be 6+, so the charge on each scandium ion is 3+.
Well, a carbocation is an ion made from one carbon and three hydrogens. The carbon only has six electrons, which is why it has a positive charge. Some other examples: Carbonate CO3 charge of -2 Bicarbonate HCO3 charge of -1 Nitrate NO3 charge of -1 Phosphate PO4 charge of -3 Sulfate SO4 charge of -2 Ammonium NH4 charge of +1
Atoms with charge are called ions. These ions have either gained or lost valence electrons to gain a net positive or net negative charge. Ions with a positive electrical charge of positive 1 (+1) are metals in the Alkali Metals Group and Hydrogen. Ions with a negative electrical charge of 1 (-1) are elements in the Halogen Group.
