Definition of electronegative in English: electronegativeadjective ɪˌlɛktrə(ʊ)ˈnɛɡətɪvəˌlɛktrəˈnɛɡədɪv 1Physics Electrically negative. Example sentencesExamples - Consequently, the more electronegative atom has a partial negative charge.
- For example, electrons in a covalent bond are assigned to the more electronegative atom.
- The less electronegative atom will have a partial positive charge since the shared electrons spend less time near it.
- The centers of corresponding ellipsoids are close, in agreement with well-known restrictions on the hydrogen bonding of electronegative atoms.
- Specifically, large electropositive or electronegative regions can reasonably attract oppositely charged entities through long-range electrostatic interactions.
2Chemistry (of an element) tending to acquire electrons and form negative ions in chemical reactions. Example sentencesExamples - Since there are two atoms bound to the sulfur atom (the less electronegative element), there must be one double bond.
- Because halogens are highly electronegative, their atoms normally retain negative charge in these compounds.
- Also, the energy has such a large negative value, because the cholesterol hydroxyl interaction with the phosphate group involves several electronegative phosphate oxygens.
- 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.
- Oxygen, the next most electronegative element, is also a powerful oxidant, as are chlorine and bromine.
