Conceptanalysis for Element MACROSCOPIC. An element is a pure substance that cannot be separated into simpler macroscopic substances with characteristic properties that differ from the original substance. MICROSCOPIC. An element is a substance composed of a single kind of atom.
Concept Attributes CRITICAL ATTRIBUTES Cl. It is a kind of matter. (macroscopic) C2. It is pure. (macroscopic) C3. Separation into parts of macroscopic size results in no change in characteristicproperties.(macroscopic) C4. It is composed of a single kind of atom. (microscopic) VARIABLE ATTRIBUTES Vl. It may exist as solid, liquid, or gas. (macroscopic) V2. Examples may have different properties. (macroscopic) V3. It may react easily or with reluctance (macroscopic) V4. Atoms may exist in various size aggregates. (rnicroscopic)
