What are the group II anions?
Group II (Cu2+, Bi3+, Cd2+, Hg2+, As3+, Sb3+, Sn4+) cations produce very insoluble sulfides (Ksp values less than 10-30) so they can be precipitated by low amounts of sulfide ion; this can be achieved by adding an acidic solution of H2S.
How many group are in anions?
Likewise, Group 16 elements form ions with a 2− charge, and the Group 15 nonmetals form ions with a 3− charge.

What are 5 anions examples?
Examples of anions include the following:
- Chlorine: Cl. –
- Hydroxide: OH. –
- Iodide: I. –
- Dichromate: Cr2O. 7–2
- Oxide anion: O. –2
- Sulfate anion: SO. 4–2
How are anions named?
Monatomic anions are named by taking the root of the element name and applying an -ide ending. Other important simple anions. Monatomic anions do not occur with multiple charges, thus each nonmetal can form only one monatomic anion, unlike some of the metals which can have multiple monatomic cations.
What are the group 4 anions?
Anions of this group are: Manganate (MnO42–), Permanganate (MnO4–), Chromate (CrO42–), Dichromate (Cr2O72–).
What anion means?
a negatively charged ion
Definition of anion
: the ion in an electrolyzed solution that migrates to the anode broadly : a negatively charged ion.
What is an anion in chemistry?
anion, atom or group of atoms carrying a negative electric charge.
What are the group 4 anions?
Anions of this group are: Manganate (MnO42–), Permanganate (MnO4–), Chromate (CrO42–), Dichromate (Cr2O72–).
Which is the anion?
An anion is a molecule or a group of molecules with one or more negative electric charges. Cations have one or more positive charges attached to them. One or more negative charges are carried by anions. Metal atoms combine to generate cations.
What are anions in chemistry?
anion, atom or group of atoms carrying a negative electric charge.
Which element is a anion?
The Creation of Anions
| Element | Anion Example | Anion Charge |
|---|---|---|
| Chlorine | Chloride | -1 |
| Fluorine | Fluoride | -1 |
| Oxygen | Oxide | -2 |

How a anion is formed?
An anion is an ion with negative charge, meaning it has more electrons than protons. Anions are formed when an atom gains one or more electrons: the gain of the negatively-charged electron(s) results in an overall negative charge.
Why are cations called anions?
Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a positively charged cation.
