What are the periodic trends in electronegativity?

What trends in electronegativity occur in a period? The trends for electronegativity is that the value increases across the periods (rows) of the periodic table. Lithium 1.0 and Fluorine 4.0 in period 2

How to tell electronegativity?

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the ...

What is the most electronegative element on the periodic table?

The elements in the second period show resemblance to the elements of the next group in period three. This happens due to a small difference in their electronegativities. This leads to the formation of a diagonal relationship. Fluorine is the most electronegative element on the periodic table. Its electronegativity value is 3.98.

What is the formula for electronegativity?

When you're using kJ/mol as units for your energies, the equation for Mulliken electronegativity is ENMulliken = (1.97×10−3) (Ei+Eea) + 0.19. Plug your values into the equation and solve for EN Mulliken . EN Mulliken = (1.97×10 −3 ) (E i +E ea) + 0.19
