Pronunciation: [aɪən]
Word
Context: "chemistry"
(noun) an ion is a tiny particle that has an electric charge. It can be positive or negative. Ions are created when atoms lose or gain electrons, which are very small parts of the atom.
Example
Sodium ions play an important role in how our bodies send messages between cells.
Example
The solution did not contain any ions, so it couldn't conduct electricity.
Example
Can you explain how an ion is formed in a chemical reaction?
Context: "physics"
(noun) an ion can also refer to charged particles that are important in physics, especially in areas like electricity and magnetism. These ions move and can create electric currents.
Example
The ion moved through the circuit, helping to power the device.
Example
Without ions, the electrical device would not work at all.
Example
What happens to the movement of ions in a magnetic field?
