Malleability in Chemistry
Malleability is a physical property of a material that describes its ability to be hammered, pressed, or rolled into thin sheets without breaking. This property is commonly observed in metals, particularly those with metallic bonding.
Factors Affecting Malleability
The malleability of a material can be influenced by several factors, including:
- Crystal Structure: Materials with a crystalline structure often exhibit greater malleability due to the ability of the crystal lattice to deform without fracturing.
- Grain Size: Finer grain sizes in a material can enhance its malleability as dislocations can move more easily through the structure.
- Temperature: Higher temperatures can increase the malleability of a material by allowing for greater atomic mobility and decreased resistance to deformation.
Examples of Malleable Materials
Several metals are known for their malleability, including:
Applications of Malleability
The malleability of metals has led to their use in various applications, such as:
- Manufacturing of thin foils and sheets for packaging
- Forming of metal components in jewelry and artistic designs
- Production of metal cans and containers
- Fabrication of metal wire and cables
Study Guide
When studying malleability, consider the following key points:
- Define malleability and distinguish it from other mechanical properties like ductility and hardness.
- Understand the atomic and crystallographic basis for malleability in metals.
- Identify factors that influence the malleability of materials and explain their effects.
- Discuss real-life examples of malleable materials and their applications in industry and everyday life.
- Conduct experiments or demonstrations to illustrate the malleability of different metals.

Physical Science
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
Relate temperature to the average molecular kinetic energy.
