Ionic
eye-ON-ik
/aɪˈɒnɪk/
Relating to or denoting chemical bonds formed by the electrostatic attraction between oppositely charged ions.
Ionic bonds typically form between metals and non-metals, leading to crystal lattice structures rather than discrete molecules.
The story behind the word. The term 'ion' was coined by Michael Faraday in 1834, derived from the Greek word 'ion,' meaning 'going' (from 'ienai,' to go). Faraday used it to describe the particles that 'go' or migrate towards the electrodes during electrolysis. The adjective 'ionic' then naturally developed to describe phenomena or bonds related to these charged particles.
Word relationships
- covalent: Involves electron sharing, rather than electron transfer and electrostatic attraction.
Commonly confused with
- Covalent: Ionic bonds involve electron transfer and electrostatic attraction; covalent bonds involve electron sharing.
Word family
- ion (noun): An atom or molecule with an electric charge due to the loss or gain of one or more electrons.
- ionization (noun): The process of converting an atom or molecule into an ion.
Collocations
- ionic bond
- ionic compound
- ionic crystal
- ionic solution
Example sentences
- "Table salt, sodium chloride, is an ionic compound formed by the transfer of electrons." Explaining a type of chemical bond.
- "Ionic compounds often have high melting points and conduct electricity when molten or dissolved in water." Discussing material properties.
- "The strong electrostatic forces in an ionic bond differ significantly from the shared electrons in a covalent bond." Comparing bond types.
Memory hook
Think of 'ION-ic' as 'I ON-ly' transfer electrons, I don't share them. ION-ic: I ON-ly transfer
When not to use
Do not use 'ionic' for bonds where electrons are shared, such as covalent bonds.
Fun facts
- Many minerals and salts are ionic compounds, forming crystal structures.
- Our bodies rely on the movement of ions (like sodium, potassium, and calcium ions) for nerve impulses and muscle contractions.
