Atom Concept Map

About this atom concept map

This concept map systematically organizes the classification logic of matter, constructing hierarchical relationships from two core dimensions, state and composition, to clearly present the categorization of matter and their internal connections.

Matter is first divided into solid, liquid and gas based on its state. By composition, it splits into pure substances and mixtures. Pure substances include elements and compounds: an element’s basic unit is an atom, which consists of electrons, protons and neutrons. Compounds are made of molecules, classified into monoatomic, diatomic and polyatomic types. Mixtures fall into homogeneous solutions and heterogeneous suspensions. Solutions are separated via simple distillation or fractional distillation, while suspensions rely on techniques like filtration and centrifugation.

The layered classification in the map showcases matter’s macroscopic states like solid, liquid, and gas, and delves into microscopic structures. It also links separation method differences, integrating matter’s existence forms, internal structures and separation techniques organically.

As a chemistry learning tool, this concept map clarifies matter classification’s core framework. From macroscopic to microscopic, from category division to operational application, it builds a systematic cognitive structure — helping grasp the material world’s organizational laws and change logic.
