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.

What is electronegativity and how is it defined?

Explain the trend of electronegativity as you move up the periodic table.

How does the number of protons in an atom affect its electronegativity?

Compare the electronegativity of aluminum and gallium based on their energy levels.

Why does phosphorus have a higher electronegativity than potassium?
