Electronegativity Trends in the Periodic Table

The video explains electronegativity, the ability of an atom to attract electrons, using fluorine as a key example. It discusses trends in electronegativity across the periodic table, noting that it increases towards fluorine and decreases down a group. The video includes practice problems comparing the electronegativity of different elements and ions, emphasizing that nonmetals are generally more electronegative than metals. It concludes with a ranking exercise of elements by their electronegativity values.
