tha hình

Definition

1. Adjective:
   • Allotropic: In chemistry, describing the property of some chemical elements to exist in two or more different physical forms (allotropes) in the same physical state. These forms have distinct structures and properties.
   • Xenomorphic: In mineralogy and petrology, describing a crystal in an igneous rock that does not have its characteristic, well-formed crystal faces because its growth was constrained by surrounding crystals.

Usage Examples

• Adjective (Chemistry):
  • Carbon là một nguyên tố tha hình, tồn tại dưới dạng than chì và kim cương. (Carbon is an allotropic element, existing as graphite and diamond.)
• Adjective (Mineralogy):
  • Trong mẫu đá này, các hạt thạch anh có dạng tha hình. (In this rock sample, the quartz grains have a xenomorphic form.)

Advanced Usage

• The term is technical and primarily used in scientific contexts (chemistry, geology). It is not common in everyday language.
• It can sometimes be seen in its variant form "thù hình", which carries the same meanings.

Variants and Related Words

• Thù hình: A variant spelling with identical meaning (allotropic, xenomorphic).

Synonyms

• Allotropic: Having multiple structural forms (e.g., carbon, sulfur, phosphorus).
• Xenomorphic: Anhedral (in mineralogy).

Related Scientific Terms

• Allotrope: One of the different physical forms of an allotropic element.
• Idiomorphic: The opposite of xenomorphic; describing a crystal with its own perfect shape.
