1 Physics Electrically negative.
- Specifically, large electropositive or electronegative regions can reasonably attract oppositely charged entities through long-range electrostatic interactions.
- The centers of corresponding ellipsoids are close, in agreement with well-known restrictions on the hydrogen bonding of electronegative atoms.
- Consequently, the more electronegative atom has a partial negative charge.
2 Chemistry (Of an element) tending to acquire electrons and form negative ions in chemical reactions.
- In the case of binary covalent compounds, the positive oxidation number is assigned to the more electropositive element, and the negative oxidation number to the more electronegative element.
- Since there are two atoms bound to the sulfur atom (the less electronegative element), there must be one double bond.
- Oxygen, the next most electronegative element, is also a powerful oxidant, as are chlorine and bromine.
- sense 2.Example sentences
- Fluorine steals electrons from hydrogen atoms because fluorine has a higher electronegativity rating.
- The effect of electronegativity dominated the analysis, suggesting that it is the major contributor.
- Atoms with widely different electronegativities will form ionic bonds, since the atom with the highest eletronegativity is able to pull an electron away from the atom with the lower electronegativity.
