Question

Metallic bonds are formed because valence electrons are mobile. Valence electrons are not confined to each atom but shared by all and create a "moving sea of electrons." Which of the following is not true about metallic bonding?

A) Metallic bonds make metals malleable.
B) Metallic bonds make metals good conductors of electricity.
C) Metallic bonds are responsible for the brittle nature of metals.
D) Metallic bonds make metals ductile.

Answer 1

The statement that is not true about metallic bonding is that metallic bonds are responsible for the brittle nature of metals. Therefore correct option is C

Step-by-step explanation:

The statement that is not true about metallic bonding is:

C) Metallic bonds are responsible for the brittle nature of metals.

Metallic bonding is the electrostatic attraction between the positively charged atomic nuclei of metal atoms and the delocalized electrons in the metal. It is this bonding that gives metals their unique properties such as malleability, ductility, and conductivity. However, metallic bonds are not responsible for the brittle nature of metals. Brittle materials, like ceramics, have covalent or ionic bonds which are stronger and less flexible than metallic bonds.
