Electronegativity, of an element

The electronegativity of an element indicates the relative ability of its atoms to attract electrons to form chemical bonds. According to the graph, as yon move across a period in the periodic table —... [Pg.11]

The now generally accepted scale of electronegativity was derived by Allred and Rochow and is known by their names. It is based on the concept that the electronegativity of an element is related to the force of attraction experienced by an electron at a distance from the nucleus equal to the covalent radius of the particular atom. [Pg.13]

Allred and Rochow [i, ii] introduced their -> electronegativity scale. They defined the electronegativity of an element X ( R) as follows y1 1 = (35904s2 ) + 0.744 Zeff is the effective charge of the nucleus acting on the electron, and rcov is the covalent radius of the atom in pm. [Pg.233]

The electronegativity of an element is its strength and ability to attract paired electrons in a covalent molecule. Electronegativity increases as you move up and over to the right on the periodic table. Fluorine is the most electronegative element. (See Figure 11.2)... [Pg.84]

The type of bond, and therefore the type of compound, that an atom will form in a given situation depends upon the relative electronegativities of the elements involved. The electronegativity of an element is a relative measure of its attraction for bonding electrons. The scale for electronegativity was based on the most electronegative element, fluorine, which has an... [Pg.116]

In spite of the widespread use of electronegativity as a unifying concept in organic chemistry, the electronegativity of an element is almost never included in the periodic table. Redressing this deficiency, Allen strikingly showed his electronegativity scale as the third dimension of the periodic table, and his vivid picture is adapted here as Fig. 1.55. [Pg.49]

What is measured by the electronegativity of an element Which element is the most electronegative ... [Pg.273]

Answer The electronegativity of an element is a measure of the ability of that element to attract a shared pair of electrons to itself. The most electronegative element is fluorine with a value of 4.0. [Pg.273]

Based on the data in Table 1, explain how the electronegativity of an element can be used to predict whether the pure substance will be a metal or a nonmetal. [Pg.144]

How does the electronegativity of an element differ from its electron affinityl... [Pg.299]
