Question

bond has a lot of free moving electrons.

• A. Ionic
• B. Metallic
• C. Covalent

Answer 1

The correct option is B Metallic

An ionic bond involves transfer of electrons, a covalent bond involves sharing of electrons, whereas, in a metallic bond, there are a lot of metal ions surrounded by free, mobile electrons.
These electrons are free to move around "cluster" of metal atoms, generally referred to as the "electron sea". This electron sea is shared by the metal atoms.
