Metallic bonding is
a type of covalent bond
a type of ionic bond
an attraction between positive and
negative ions
an attraction between positive ions
and electrons

liquid
solid
gas
an alloy
Fill in the blank to complete each statement.
5. An attraction between a positive metal ion and surrounding electrons is
a(n)
bond.
6. Metals typically have
melting points.
7. The metal fins that cool a motorcycle’s engine make use of the high
conductivity of metals.
8. Metals are often used to make wire because they are
.
9. Metals are used in electrical wires because they have high
conductivity.
10. Nonmetals are unlikely to form metallic bonds because their
are strongly held.
