proposed an electronegativity scale in which the Mulliken electronegativity, ΧMis related to the electron affinity EAv(a measure of the tendency of an atom to form a negative species) and the ionization potential IEv(a measure of the tendency of an atom to form a positive species) by the ...
Allred and Rochow suggest a scale of electronegativity based upon the electrostatic force of attraction between the nucleus and the valence electrons. The values expressed here are converted to the Pauling scale (see below). The Allred-Rochow electronegativity is often denoted as ΧAR ...

You can use trends in ionization energy and electronegativity to predict whether two elements will form ionic or covalent compounds. Lastly, the nuclear charge increases as you go across and down the table, while the shielding stays constant across the periods, but increases as you go down the ...
Electronegativity of elements increases in moving left to right and from bottom to top in the periodic table. Atoms are more likely to accept electrons, if their outer shells are almost full, and they are less shielded from the nucleus. More shells are less shielded from the nucleus, as the...

For example, which element has greater electronegativity, potassium or phosphorus? The answer can be found by looking at a table of electronegativity values (Figure 1), or remembering the trend that electronegativity increases across a period (Figure 2). The correct response to the question is ...
Electronegativity Trends in the Periodic Table Electronegativity follows specific trends across the periodic table. Going down a group, there is a decrease in electronegativity because the atomic size increases, which means the valence electrons have to be even farther from the nucleus, making them les...
