Definition of electronegative in English:



  • 1Physics
    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.’
    • ‘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.’
  • 2Chemistry
    (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.’
    • ‘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.’
