CHEMICAL MATTER Meaning and
Definition
-
Chemical matter refers to the physical substances that exist in the natural world and are composed of atoms or molecules. It encompasses a wide range of materials, including elements, compounds, and mixtures. Chemical matter is characterized by the presence of chemical bonds between atoms that determine its chemical properties.
Elements are the fundamental building blocks of chemical matter and cannot be broken down into simpler substances. Each element is represented by a unique symbol and possesses specific atomic properties, such as atomic number and mass.
Compounds, on the other hand, are substances formed by chemically combining two or more elements in fixed proportions. These combinations occur through chemical reactions, resulting in new substances with distinct properties from their constituent elements.
Mixtures are combinations of two or more substances that are physically mixed together but not chemically bonded. The components of a mixture can retain their individual properties and can be separated by physical means, such as filtration or distillation.
Chemical matter exists in various states, including solid, liquid, and gas, depending on the arrangement and movement of its constituent particles. These states can change through physical processes, such as melting, boiling, or condensation.
The study of chemical matter is a fundamental aspect of chemistry, aiming to understand its composition, behavior, and the interactions between different substances. Chemical matter plays a crucial role in numerous aspects of daily life, from the substances we encounter and consume to the development of materials for industries and technologies.
Etymology of CHEMICAL MATTER
The word "chemical" originated from the Late Latin word "chemicus" or "chimicus", which itself was derived from the Greek word "khēmeía" (χημεία), which refers to alchemy. Alchemy was an ancient practice that aimed to understand the nature of matter and transform substances. The term "chimicus" eventually evolved into "chemical" in English, which encompasses the field of modern chemistry.
The word "matter" has its roots in the Latin word "mater" which means "substance" or "material". This term has been used for centuries to describe physical substances of various kinds, including elements, compounds, and mixtures. Over time, "matter" has become a fundamental concept in science, referring to anything that possesses mass and occupies space.
