Trend-wise, as one moves from left to right across a period in the modern periodic table, the electronegativity increases as the nuclear charge increases and the atomic size decreases. However, if one moves down in a group , the electronegativity decreases as atomic size increases due to the addition of a valence shell , thereby decreasing the ...
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.
See also: Electronegativities of the elements (data page) There are no reliable sources for Pm, Eu and Yb other than the range of 1.1–1.2; see Pauling, Linus (1960).
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.

Carbon forms covalent bonds with other non-metals with an oxidation state of −4, −2, +2 or +4. [25] Carbon is the fourth most abundant element in the universe by mass after hydrogen, helium and oxygen [31] and is the second most abundant element in the human body by mass after oxygen, [32] the third most abundant by number of atoms.

Investigators said they had “serious concerns” about “credible reports of sexual assault and other sexual misconduct" by the officers.
A list of the electron affinities was used by Robert S. Mulliken to develop an electronegativity scale for atoms, equal to the average of the electrons affinity and ionization potential. [ 2 ] [ 3 ] Other theoretical concepts that use electron affinity include electronic chemical potential and chemical hardness .
