Electronegativity chart helps provide the relationship between the number of protons and electrons and the distance of the outermost electron shell from the nucleus. You can refer to the following article on electronegativity chart for more information...
The tendency of an atom to attract bonding pairs of electrons is measured using electronegativity. The most common scale used to measure electronegativity is Pauling scale. The most electronegative atom in the periodic table is Fluorine, at 4.0 and the least electronegative atoms are cesium and francium. Let us look at some information related to electronegativity chart bonds.
Electronegativity Chart Bonds
Electronegativity was first discovered by Linus Pauling in the year 1932. Pauling got the idea of electronegativity when he discovered valance bond theory. This theory helped him realize the relationship between one chemical element with another element. It is not possible to measure electronegativity of an element directly as it depends on the properties of an element.
Electronegativity is basically the property of an element that helps in attracting a pair of electrons or a single electron towards it. The trends show that the electronegativity of an atom or element is directly related to its atomic number or the space between valance electrons and nucleus. Pauling came up with Pauling scale which is the simplest way to calculate electronegativity of an element in the Periodic table. It has been found that the difference in electronegativity chart, varies with the environment of the element. The electronegativity chart bonds is based on the molecule having polar.
The above electronegativity chart shows that the measure of attraction between an atom for electrons in a chemical bond is electronegativity. When the atom shows higher electronegativity, it is better able to attract bonding electrons. Ionization energy is related to electronegativity as low ionization electrons exhibit low electronegativity. This is because their nuclei does not have a strong attractive force on electrons. When you refer to a decreasing electronegativity, you will find, electronegativity decreases as atomic number increases. This is because of the distance between valance electrons and nucleus.
Electronegativity Trends
There are particular electronegativity trends that are seen in the periodic table. When one moves left to right in the periodic table, the atomic radius of the elements decreases, ionization energy increases and electronegativity increases. When one moves from the top to the bottom in the periodic table, the atomic radius increases, the ionization energy decreases and the electronegativity too decreases.
This was all about the electronegativity chart of the periodic table elements. You may find the above chart given above based on Pauling scale useful in finding out the electronegativity of each element.
