Examples of anions include the following:
- Chlorine: Cl. –
- Hydroxide: OH. –
- Iodide: I. –
- Dichromate: Cr2O. 7–2
- Oxide anion: O. –2

Which ion is an example of anion?
Ions with a negative charge are called anions. Many normal substances exist in the body as ions. Common examples include sodium, potassium, calcium, chloride, and bicarbonate.
What are the example of anion and cation?
Cation vs anion chart
| Cation | Anion | |
|---|---|---|
| Charge | Positive | Negative |
| Electrode attracted to | Cathode (negative) | Anode (positive) |
| Formed by | Metal atoms | Non-metal atoms |
| Examples | Sodium (Na+), Iron (Fe2+), Ammonium (NH4+) | Chloride (Cl–), Bromide (Br–), Sulfate (SO42–) |

What is the most common anion?
The most abundant cations present in water are calcium (Ca), magnesium (Mg), sodium (Na), and potassium (K); the most abundant anions are bicarbonate (HCO3), chloride (Cl), and sulfate (SO4).

Is potassium an anion?
It is an alkali metal cation, an elemental potassium, a monovalent inorganic cation and a monoatomic monocation. Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells.
Is co2 an anion?
The carbon dioxide radical anion (CO2•–) is a highly reactive intermediate that is routinely accessed through electrochemical reduction of CO2.
Is water a cation or anion?
The positively charged ions are called cations, and the negatively charged ions are called anions. Because water is globally neutral electrically (otherwise you would get an electric shock when you put your hand in water) the number of positive charges is identical to the number of negative charges.
Is nh4 a cation or anion?
“Ammonium is a polyatomic cation with a chemical formula NH4+.
Is Na+ an anion or cation?
Opposite charges attract each other (positive charge attracts negative charge, and vice versa), so a collection of cations and anions is stable. Neutral sodium atom (Na) becomes sodium cation (Na+) by releasing an electron.
What ion is a cation?
What is a cation? A cation is an ion with positive charge, which means it has more protons (positively-charged particles) than electrons (negatively-charged particles). Cations are formed when an atom loses one or more electrons: the loss of the negatively-charged electron(s) results in an overall positive charge.
Is Iodine a anion?
Iodine is a nonmetallic element. With this, it has the tendency to gain electrons and become an anion. The anionic form of iodine is I− .
What is a anion in chemistry?
anion, atom or group of atoms carrying a negative electric charge.
Is copper a cation or anion?
List of Ions in the CCCBDB
| Species | Name | charge |
|---|---|---|
| Cu– | Copper atom anion | -1 |
| Cu+ | Copper atom cation | 1 |
| LiH– | lithium hydride anion | -1 |
| LiH+ | lithium hydride cation | 1 |
Is hydrogen a cation?
Hydrogen forms the only cation that has no electrons, but even cations that (unlike hydrogen) still retain one or more electrons are still smaller than the neutral atoms or molecules from which they are derived.
Is so4 a cation or anion?
This entity has been manually annotated by the ChEBI Team. The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO2−4. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life.
Is oxygen anion or cation?
Is oxygen a cation or anion? Oxygen is neither a cation or an anion because it has no charge. Oxygen makes up around 20% of the air, and it’s a highly reactive gas. There are various substances that include oxygen, in addition to pure oxygen in the air and pure oxygen dissolved in water.
Is iron anion or cation?
Iron is a transition metal; thus, it is a type II cation.
Is gold a cation or anion?
The transition metals are typically regarded as cation-forming elements. However, gold is a notable exception since it is stable as an isolated anion (Au– or auride).
Is sodium an anion?
(4,9,12,18) Investigations concluded that Na– is a “genuine” anion in which both the [Ne] core and the 3s valence electrons interact very weakly with their surroundings.
Is Potassium a cation?
Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells.
