electrovalency
Very lowTechnical, Academic
Definition
Meaning
A measure of the power of an atom or group to combine with others by the transfer of electrons, forming ionic bonds; the number of charges an ion possesses.
In chemistry, the concept of combining capacity expressed in terms of the number of electrons lost, gained, or shared to achieve a stable electronic configuration. More broadly, it can refer metaphorically to the binding force or attractive power in non-chemical contexts.
Linguistics
Semantic Notes
This term is almost exclusively used in the context of inorganic and theoretical chemistry. It is largely synonymous with 'ionic valence' and stands in contrast to 'covalency'.
Dialectal Variation

Examples
By Part of Speech
adjective
British English
- The electrovalent bond is strong.
American English
- The electrovalent compound dissolved easily.
Examples
By CEFR Level
- This word is too difficult for A2 level.
- Sodium has an electrovalency of +1.
- The electrovalency of an element determines how it forms ionic compounds.
- While covalency involves electron sharing, electrovalency is characterised by complete electron transfer, resulting in discrete ions.
Learning
Memory Aids
Mnemonic
Imagine an ELECTROn stealing VALENCe (strength) from another atom, creating an ELECTROVALENT (ionic) bond.
Conceptual Metaphor
ELECTRON TRANSFER IS A GIFT/TAKING (The atom 'gives' or 'takes' electrons to achieve stability).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'ковалентность' (covalency). The Russian term is 'электро валентность', but it is a direct calque.
Common Mistakes
- Misspelling as 'electrovalencey' or 'electrovalance'.
- Using it to describe covalent bonds.
- Pronouncing the 'c' as /k/ instead of /s/.

FAQ
Frequently Asked Questions
No. Valence is a broader term for combining capacity. Electrovalency is a specific type of valence involving electron transfer to form ionic bonds.
Typically, no. Electrovalency is usually a small whole number (e.g., +1, +2, -1) as it corresponds to the number of electrons transferred.
In modern chemistry, the terms 'ionic valence' or simply 'charge on the ion' are often preferred, but 'electrovalency' remains a valid technical term.
Covalency, which involves the sharing of electron pairs between atoms.
