electronegativity

1 8.1

The ability of an atom to pull electrons toward itself when it forms a bond

noun
/ˌɛlɛkˌtroʊnɪˈɡætɪvɪti/

Specialized

: electronegatividad

Due to the similar electronegativity and atomic radius of Co and Ni, Co could take up the site of Ni in the B2 structure.

So we're going to end with that and we'll continue with Electronegativity on Friday.

Examples

Fluorine has the highest electronegativity among the elements, making it very effective at attracting electrons.
The concept of electronegativity explains why some atoms attract electrons more strongly than others in a bond.
Instead, it will experience a high level of electronegativity because of the attraction of many electrons with a negative charge.

Morphology

electronegativity = electronegative (semi-transparent) = electro + negative + ity

The noun is transparently formed from the adjective 'electronegative' plus '-ity', but the chemistry-specific meaning is specialized rather than fully predictable for general learners.

Etymology

Electronegativity comes from electron ('a very small negative particle') and negative ('minus' or 'negative in charge'), so it literally names how strongly an atom 'pulls' electrons toward itself when it makes a bond.
