Visualise electronegativity trends across the periodic table and understand how electronegativity relates to element type and bonding behaviour.
Electronegativity Trend
Most electronegative: Fluorine (F) = 4.0 | Least electronegative shown: Caesium (Cs) ≈ 0.7
Electronegativity increases across a period (metals → non-metals) and decreases down a group.
