Question

Complete the passage about metallic bonding.

Answer 1

In metallic bonding, valence electrons of metals move freely between neighbouring atoms. metals are ductile

because the forces that hold their atoms together are weak.

Explanation:

• Metallic bonds are the force which holds atoms together in a metal.

• Valence electrons present in the metals are freely moving between the other neighbouring atoms. The interaction between the positive ions which electrons leave behind and the valence electrons give the binding force which able to hold the metallic crystal together as it is.

• In metals, the electrons are free to travel from one metal to another metal. This speciality is the reason for their electric conductivity. And this shows that the metal-metal bond is weak in metal.
