Ionic bonds form as a result of the electrostatic attraction between
dipoles.
electrons.
ions.
nuclei.
A single covalent bond involves the sharing of
only one electron.
two electrons.
three electrons.
a variable number of electrons, which depends on the bonding atoms.
The measure of an atom’s ability to attract electrons is its
electronegativity
polarization.
ionization
electron affinity
Atoms that are bonded with an electronegativity difference of 0 to 0.3 are generally considered to be
negatively charged compounds.
nonpolar-covalent compounds.
polar-covalent compounds.
ionic compounds.
What is the apparent charge on the chlorine atom in the molecule HCl?
+1
-1
δ+
δ-
Atoms seldom exist as independent particles in nature because
as single particles, most atoms have low potential energy.
their electronegativity is much lower when they combine with other atoms.
atoms are more stable when they combine with other atoms.
neutral particles are rare.
When an atom completely gives up its valence electrons to another atom, they form a bond that is considered to be
purely ionic.
partially ionic.
polar-covalent.
nonpolar-covalent.
You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the
distance between the atoms’ nuclei.
difference in the atoms’ electronegativities.
atoms’ atomic radii.
number of atoms in the compound.
