Why do metals have multiple charges?
Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration. In addition, the majority of transition metals are capable of adopting ions with different charges. Because most transition metals have two valence electrons, the charge of 2+ is a very common one for their ions.
Which metals form two ions with different charges?
The correct answer is iron (Fe). It falls in the transition group, and can form two cations, with charges of +2 or +3.
What metals have multiple charges that are not transition metals?
Many of the transition metals (orange) can have more than one charge. The notable exceptions are zinc (always +2), silver (always +1) and cadmium (always +2).

Why transition metals have multiple oxidation states?
Transition metals can have multiple oxidation states because of their electrons. The transition metals have several electrons with similar energies, so one or all of them can be removed, depending the circumstances. This results in different oxidation states.
How do metals have different charges?
The charge on a transition metal atom is equal to its oxidation state and can vary from +1 to +7. Transition metals can lose electrons more readily than other elements because they have unstable electrons in their outer orbitals.
What metals form multiple ions?
Metals that form more than one cation.
| Cation | Systematic Name | Common Name |
|---|---|---|
| Fe 2+ | iron(II) | ferrous |
| Fe 3+ | iron(III) | ferric |
| Co 2+ | cobalt(II) | cobaltous* |
| Co 3+ | cobalt(III) | cobaltic* |
What ionic charge will each group form?
Group I (alkali metals) carry a +1 charge, Group II (alkaline earths) carry a +2, Group VII (halogens) carry -1, and Group VIII (noble gases) carry a 0 charge. Metal ions may have other charges or oxidation states. For example, copper usually has a +1 or +2 valence, while iron typically has a +2 or +3 oxidation state.
Which metals have multiple ions?
Metals that form more than one cation.
| Cation | Systematic Name | Common Name |
|---|---|---|
| Mn 3+ | manganese(III) | manganic* |
| Fe 2+ | iron(II) | ferrous |
| Fe 3+ | iron(III) | ferric |
| Co 2+ | cobalt(II) | cobaltous* |
What are transition metals charges?
What are some metals that form multiple ions?
Which metals form cations of various charges?
Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).
Why do transition metals have different charges?
Transition metals can lose electrons more readily than other elements because they have unstable electrons in their outer orbitals. Some oxidation states are more common than others for different transition metals because these states are relatively stable.
Are all metals positively charged?
In general, metals lose electrons to form positively charged ions (Fe+2, Au+3, Ag+), and nonmetals gain electrons to form negatively charged ions. A positive charge is also known as a cation.
What are the charges on the metals?
If you look at the periodic table, you will find the metals in groups (from one to 16). Group one is composed of metals that have a +1 charge, while all the metals in groups 2,3,4,5,6,7,8,9,10,11,12, and 16 have a charge +2. Then, metals in groups thirteen and fifteen have a charge of +3 . Finally, all the metals in group 14 have a +4 charge.
How do you determine the charge of transition metals?
To determine the charge on a given transition metal atom, you have to consider what element it is, the charges on the other atoms in the molecule, and the net charge on the molecule itself. The charges are always whole numbers, and the sum of all the atomic charges equals the charge on the molecule.
