Electronegativity (Noun)
Meaning
(chemistry) the tendency of an atom or radical to attract electrons in the formation of an ionic bond.
Classification
Nouns denoting attributes of people and objects.
Examples
- In chemical compounds, elements with higher electronegativity typically bond to the atom at the left on the periodic table due to increased likelihood to release valence electron of second compound into electro-static surrounding nucleus between either charges either lesser-greatest oppositely-electrons free-drained molecular single single variable velocity changes along varied conflux chain synthesis motion matter which relative rate of atomicity dependent valency electronegativity tendency pulling electron sharing.
- The water molecule is polar because oxygen has higher electronegativity than hydrogen.
- A difference in electronegativity between two bonded atoms can lead to an uneven distribution of electrons, creating a dipole.
- When two atoms with different electronegativities form a covalent bond, the atom with the higher electronegativity typically pulls the shared electrons closer to itself.
- In the molecule HF, the fluorine atom has a higher electronegativity than the hydrogen atom, resulting in a polar covalent bond.
