Electronegativity. Electronegativity is a measure of an atom's ability to attract the shared electrons of a covalent bond to itself. If atoms bonded together have the same electronegativity, the shared electrons will be equally shared. If the electrons of a bond are more attracted to one of the atoms (because it is more electronegative), the electrons will be unequally shared. Electronegativity is mainly used for two purposes; To predict if an atom will form an ionic or a covalent bond. To predict if the resulting molecule will be polar or nonpolar.

Electronegativity of Argon is —. Electron Affinity. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as:. the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.
$\begingroup$ then why does Krypton, Radon and Xenom have an electronegativity value? They are noble gases too so they shouldn't be electronegative. $\endgroup$ – MartianCactus Jul 24 '16 at 8:25 $\begingroup$ Noble gases have their outer s and p orbitals filled with electrons (just s in case of He).

This affinity is known as the first electron affinity and these energies are negative. By convention, the negative sign shows a release of energy.

In HF, the fluorine atom is much more electronegative than the hydrogen atom. In general electronegativity is the measure of an atom's ability to attract electrons to itself in a covalent bond. Because fluorine is the most electronegative element, the electrons tend to "hang out" more toward the fluorine atom when fluorine is covalently bonded to other atoms.

In general, nonmetal atoms have higher electronegativities than metal atoms. In the periodic table, electronegativity typically increases in moving across a period
Across a period from left to right the electronegativity of atoms increases. 2019-03-02 · Electronegativity is a measure of the attraction of an atom for the electrons in a chemical bond. The higher the electronegativity of an atom, the greater its attraction for bonding electrons . Ionization Energy 2020-09-02 · Mulliken electronegativity is a slightly different way of measuring electronegativity than is used in the Pauling table above. To find Mulliken electronegativity for a certain atom, find that atom's first ionization energy. This is the energy required to make the atom discharge a single electron.
