The Definition Of Electronegative Element

The least electronegative element is cesium 0 79. Note that older texts list both francium and cesium as least electronegative at 0 7 but the value for cesium was experimentally revised to the 0 79 value. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Relating to or charged with negative electricity.

The definition of electronegative element. The pauling scale is the most commonly used. The higher the electronegativity is the more it attracts the electrons towards it. Referring to an element whose uncharged atoms have a tendency to ionize by adding electrons thus becoming anions for example oxygen fluorine chlorine. Having a negative electric charge.

Electronegativity definition electronegativity is a chemical property that measures the tendency of an atom to attract electrons towards itself. Electronegativity is affected by the atomic number and the distance between the valence electrons and its nucleus. The most electronegative element is fluorine followed by oxygen chlorine and nitrogen. An example of a highly electronegative element is fluorine.

An example of an electropositive i e low electronegativity element is cesium. Values for electronegativity run from 0 to 4. The opposite of electronegativity is electropositivity so you could simply say cesium is the most electropositive element. Fluorine the most electronegative element is assigned a value of 4 0 and values range down to caesium and francium which are the least electronegative at 0 7.

Highly electropositive elements have a strong tendency to form. Electronegative element play an element whose atoms have a tendency to accept electrons and form negative ions e g oxygen sulfur chlorine etc. In an element group the electronegativity decreases as atomic number increases as a result of increased distance between the valence electron and nucleus greater atomic radius. The least electronegative most electropositive element is cesium followed by rubidium potassium and barium.

Capable of acting as a negative electrode. Electronegativity is used to predict whether a bond between atoms will be ionic or covalent. Tending to attract electrons to form a chemical bond. Atoms with high electronegativity tend to form negative ions.

Electronegative e lek tro neg ah tiv bearing a negative electric charge. Electronegativity is a chemical property which describes how well an atom can attract an electron to itself.
