Electronegativity is not a uniquely defined property and may depend on the definition. The suggested values are all taken from WebElements as a consistent set. Many of the highly radioactive elements have values that must be predictions or extrapolations, but are unfortunately not marked as such.
Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. [1] An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the ...

[45] [49] In general, orbitals with the same value of n + ℓ are similar in energy, but in the case of the s orbitals (with ℓ = 0), quantum effects raise their energy to approach that of the next n + ℓ group. Hence the periodic table is usually drawn to begin each row (often called a period) with the filling of a new s orbital, which ...
The average American woman weighs about 170 pounds and stands about 5 feet, 4 inches tall. But it’s important to remember that these averages are mathematical calculations and don’t ...
Values are given for the elements in their most common and stable oxidation states. See also: Electronegativities of the elements (data page) ^ Electronegativity of francium was chosen by Pauling as 0.7, close to that of caesium (also assessed 0.7 at that point).
