Check out the full States of matter playlist here: https://youtube.com/playlist?list=PLSQl0a2vh4HAcadC8xfE0VtGhfHdrECNO&si=aLyVfcDx3Xp257S6 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 bottom left.
