Answer 2

Answer:

c) soft is not a physical property of metals.

Explanation:

Metal is an element that readily forms positive ions and has metallic bonds.

• Ductility - Metals can be hammered and transformed into wires. This is called being ductile. Examples are Zinc(Zn), Copper(Cu), Iron(Fe) etc.
• Sonorous - It is a property of materials to produce deep sound. Examples are Mercury(Hg), Silver(Ag) etc.
• Soft - Metals are not soft. All the metals are hard except few alkali metals.
• Malleable - Metals can be hammered and drawn into sheets. This property is called malleable. Examples are Gold(Au), Aluminium(Al) etc.
