검증된 단계별 안내1
Understand that the modern classification system of matter is based on its composition and properties.
Recognize that matter is broadly classified into three categories: elements, compounds, and mixtures.
Elements are pure substances that consist of only one type of atom and cannot be broken down into simpler substances by chemical means.
Compounds are substances formed when two or more elements are chemically bonded together, and they have fixed proportions.
Mixtures are combinations of two or more substances that are not chemically bonded and can be separated by physical means.
