Electronegativity - Electronegativities of The Elements

Electronegativities of The Elements

Periodic table of electronegativity using the Pauling scale
→ Atomic radius decreases → Ionization energy increases → Electronegativity increases →
Group → 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

Famous quotes containing the word elements:

    “Kitsch is the daily art of our time, as the vase or the hymn was for earlier generations. For the sensibility it has that arbitrariness and importance which works take on when they are no longer noticeable elements of the environment. In America kitsch is Nature. The Rocky Mountains have resembled fake art for a century.”
    —Harold Rosenberg (1906–1978)
