Document Summary
Atoms and molecules are packed close to each other in fixed locations. Crystalline - solid matter may be this, its atoms and molecules arrange in fixed volume and rigid shape geometric patterns with long-range, repeating order. Atoms or molecules occupy specific positions to create a well-ordered, three-dimensional structure. Amorphous - atoms or molecules do not have long-range order. Anything that occupies space and has mass. Composed of atoms (submicroscopic particles that are the fundamental building blocks. Atoms are bonded together to form molecules (two or more atoms joined to one another of matter) in specific geometric arrangements) Classifying matter according to its state: solid, liquid, and gas. Atoms or molecules are separated by large distances and are free to move relative to one another. Compressible - because the atoms or molecules that compose gases are not in contact with one another. Classifying matter according to its composition: elements, compounds, We can classify matter according to its composition.
