What are positive and negative ions examples?
Positive ions are cations and are typically metals like copper or sodium. Negatively-charged ions are anions, formed from nonmetallic elements like oxygen and sulfur.
What is an example of a negative ion?
Examples of Negative Ions Fluoride is sometimes added to community water supplies. Your dentist may also give you a fluoride treatment. The negative charge (fewer protons than electrons) for an anion is shown by a number and minus sign after the formula. If there’s just a minus sign, it means the charge is minus 1.
What is positive ion?
Positive ions are formed by atoms or molecules suffering an inelastic collision with an energetic electron in which an electron is lost from the atom or molecule (electron impact ionization). The degree of ionization of the plasma depends strongly on the electron density and energy distribution in the gas.

Difference between Anion and Cation
| Cation | Anion |
|---|---|
| Example – Sodium Ion (Na + ) | Example – Chloride Ion (Cl – ) |
| Sodium (Na) has 11 protons and 11 electrons Overall charge is 0 | Chlorine (Cl) has 17 protons and 17 electrons Overall charge is 0 |
What is the name of a positive ion?
cations
Positively charged ions are called cations; negatively charged ions, anions.
What are positive ions called?
The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
What is ion give example?
Examples of Ions
| Cation | Anion | Common Name |
|---|---|---|
| H+ | Cl- | hydrochloric acid |
| Li+ | Br- | lithium bromide |
| K+ | I- | potassium iodide |
Where are positive ions?
In nature, positive ions are commonly formed by strong winds, dust, humidity, and pollution. They are at their highest levels just before an electrical storm.
