Classify the bonds formed between each pair of elements based on electronegativity values in the following table: Element Sc Be H P S I Br Cl O F Electronegativity 1.3 1.5 2.1 2.1 2.5 2.5 2.8 3.0 3.5 4.0 S-I,,,,,H-Br,,,,H-P,,,,S-O,,,,Be-F,,,,Be-Cl,,,,Sc-O Ionic: polar covalent: nonpolar covalent:
In a covalent bond between two atoms, the more electronegative atom will attract more electron density toward itself, producing a polar bond. The more electronegative element will carry a partial negative charge, whereas the less electronegative element will carry a partial positive charge. The direction of the bond dipole is always toward the more electronegative element. This is often indicated by an arrow, as shown in the figure. The magnitude of the bond polarity can be estimated by using the...
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
