Примери за electronegativity

• Chapter 1 starts off with a comprehensive summary of basic chemical principles, such as atomic structure, ionic radii, electronegativity and solubility products.

• An atom's electronegativity is affected by both its atomic number and the distance between the valence electrons and the nucleus.

• Electronegativity is a chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself.

• The oxidizing tendency of peroxides is related to the electronegativity of the substituents.

• The atomic orbital energy correlates with electronegativity as more electronegative atoms hold their electrons more tightly, lowering their energies.

• Elements in the same group tend to show patterns in atomic radius, ionization energy, and electronegativity.

• Conversely, bonds to other atoms are very strong because of fluorine's high electronegativity.

• The trifluomethyl group has a significant electronegativity that is often described as being intermediate between the electronegativities of fluorine and chlorine.

• Since fluorine is a relatively small atom with a large electronegativity, its covalent radius is difficult to evaluate.

• Of the elements within d-block, zirconium has the fourth lowest electronegativity after yttrium, lutetium and hafnium.

• The solute and solvent should have similar electronegativity.

• Elements with low electronegativity, such as most metals, easily donate electrons and oxidize they are reducing agents.

• All group 2 elements are electropositive towards carbon and electronegativity decreases down the row.

• Thiopyrylium salts are less reactive than the analogous pyrylium salts due to the lower electronegativity of the sulfur atom.

• Their strong acidity is attributed to the electronegativity of the trifluoromethyl group that stabilizes the negative charge.
