Chemistry - Periodic Table - Periodic trends - electronegativity - Electronegativity Map

Show the periodic table color-coded by Pauling electronegativity values (heat map: red = high EN like F=4.0, blue = low EN like Cs=0.7, gray = noble gases). Interactive features: 1) Hover over any element to see its EN value. 2) Click 'Show Period 3' - highlights the trend increasing L→R: Na(0.9), M
