Which of the following is not a
type of chemical bonding? (A) Covalent, (B) nuclear, (C)
metallic, or (D) ionic.
There are three main types of
chemical bonding that we’ll encounter in chemistry. The first is covalent bonding. This type of bonding is typically
found between nonmetal elements. It involves the sharing of outer
electrons to create a chemical bond. When atoms bond covalently, they
can form simple molecules like water or they can form large repeating network
covalent structures, like graphite. Then there’s ionic bonding. Ionic bonding primarily occurs
between nonmetal and metal elements. This type of bonding is caused by
an electrostatic attraction between oppositely charged ions. This is the type of bonding you see
in table salt, which has the chemical formula NaCl or sodium chloride.
The final kind of bonding is
metallic bonding, which, as the name suggests, occurs between metals. This type of bonding features
electrons that are shared between the metal nuclei that flow around the nuclei like
a sea of electrons. So as we can see, answer choices
(A), (C), and (D) all refer to types of chemical bonding. Nuclear does not. Instead, it refers to a type of
chemical process that generally results in a change to the nucleus of an atom.
