Electronegativity Periodic Trend - Using the Periodic Table to help determine electronegativity!

The video explains electronegativity, the tendency of an atom to attract electrons, using a tug-of-war analogy. It discusses trends in electronegativity on the periodic table, noting it increases from bottom to top and left to right. The video explains these trends using examples, highlighting the role of energy levels and proton count. It emphasizes that energy levels are more significant than nucleus strength when comparing elements. Examples include comparisons between aluminum and gallium, rubidium and iodine, and potassium and phosphorus.
