What are the trends for electronegativity in the periodic table?
Electronegativity is represented on a scale from 0.7 to 4.0. Francium has the lowest value, 0.7, while Fluorine has the highest value at 4.0. So, as you move from the bottom left to upper right, electronegativity increases. As you move left to right across a period, electronegativity increases. As you move down a group, electronegativity decreases.
