Problem 13 : Describe the formation of a metallic bond in a metal. How does metallic bonding contribute to the properties of metals, such as electrical conductivity and malleability?
Solution :
In metallic bonding, positively charged metal ions (cations) are surrounded by a “sea” of delocalized electrons. The electrons are free to move throughout the metal lattice, contributing to the electrical conductivity and malleability of metals.
Metallic Bond Formation:
- Metal atoms release their valence electrons, creating a sea of mobile electrons.
- The positive metal ions (cations) are held together in a regular lattice structure.
- The delocalized electrons move freely and form a “glue” that holds the metal ions together.
Contribution to Properties:
- Electrical Conductivity: Delocalized electrons can carry electric current, making metals good conductors.
- Malleability: The mobility of electrons allows metal ions to slide past each other, making metals malleable and ductile.
