What is the difference between symmorphic and homomorphic?

Definitions

symmorphic

- Describing a crystal structure that has the same symmetry as its chemical composition.

- Referring to a mineral or compound that has a symmetrical arrangement of atoms or ions.

- Talking about a material that has a uniform and consistent internal structure.

homomorphic

- Describing a crystal structure that has the same shape but different chemical compositions.

- Referring to a mineral or compound that has a similar external appearance but different internal structures.

- Talking about a material that has a consistent external shape but varying internal structures.

List of Similarities

• 1. Both words describe the structure of materials.
• 2. Both words are used in the field of mineralogy and crystallography.
• 3. Both words involve the concept of symmetry.
• 4. Both words can be used to describe the internal structure of materials.

What is the difference?

• 1. Definition: Symmorphic describes a crystal structure that has the same symmetry as its chemical composition, while homomorphic describes a crystal structure that has the same shape but different chemical compositions.
• 2. Composition: Symmorphic emphasizes the relationship between symmetry and chemical composition, while homomorphic emphasizes the similarity in external shape.
• 3. Identification: Symmorphic can aid in identifying a mineral or compound based on its internal structure, while homomorphic can make identification more challenging due to the similarity in external shape.
• 4. Usage: Symmorphic is less commonly used than homomorphic in everyday language and is more specific to the field of crystallography and mineralogy.

📌

Remember this!

Symmorphic and homomorphic are both terms used to describe the structure of materials, particularly in the field of mineralogy and crystallography. The difference between the two lies in their emphasis on symmetry and chemical composition (symmorphic) versus external shape (homomorphic). Symmorphic implies a uniform and consistent internal structure, while homomorphic implies variation in internal structure, making identification more challenging.
