Answer:
Iron and Lithium are the two substances which are held by metallic bond.
Step-by-step explanation:
- The metallic bond is a kind of chemical bond between positively charged atom and also the sharing of the free electrons among those positively charged ions.
- The Metallic bond elements have higher melting and boiling point and they are also called as the chemical atom between metal atoms.
- In Metallic bonding the outer shell electrons are loosely coupled and their adjacent atoms can overlap and they are free to move through the lattices.
The following are some of the characteristics of elements which have Metallic Bonding :
- Opacity
- Strength
- Thermal and Electrical resistivity
- Conductivity
- Malleability and Ductility
- Luster
