Answer:
metallic bonds.
Step-by-step explanation:
Generally, compounds that are ductile and excellent conductor of electricity have metallic bonds between them.
These compounds are usually metals.
- Metallic bond join that atoms of metals and alloys together.
- The formation of this type of bond is favored by large atomic radius, low ionization energy and a large number of electrons in their valence shell.
- The physical properties of metals like ductility, malleability, electrical and thermal conductivity all results from metallic bonds.
