A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together is called a(n)
The electrostatic attraction between positively charged nuclei and negatively charged electrons permits two atoms to be held together by a(n)
decrease their potential energy, thus creating more-stable arrangements of matter.
As atoms bond with each other, they
When atoms share electrons, the electrical attraction of an atom for the shared electrons is called the atom's
If the atoms that share electrons have an unequal attraction for the electrons, the bond is called
one atom usually attracts electrons more strongly than the other.
Nonpolar covalent bonds are not common because
The greater the electronegativity difference between two bonded atoms, the greater the percentage of ____ in the bond.

After drawing a Lewis structure, one should
Bonding in molecules or ions that cannot be correctly represented by a single Lewis structure is
Chemists once theorized that a molecule that contains a single bond and a double bond split its time existing as one of these two structures. This effect became known as
ratio of the combined ions present in a sample.
The chemical formula for an ionic compound represents the
A formula that shows only the types and numbers of atoms combined in a single molecule is called a(n)
The chemical formula for water, a covalent compound, is H2O. This formula is an example of a(n)
