Answer: The wire is still copper and does not change by cutting it
Explanation:
Democritus postulated that all materials were composed of these tiny particles called as "atomos".
Daltons postulates are:.
1. All matter is made of very tiny particles called atoms.
2. Atoms is indivisible.
3. Atoms of a given element are identical in mass and chemical properties.
4. Atoms of different elements have different masses and chemical properties.
5. Atoms combine in the ratio of small whole numbers to form compounds.
6. The relative number and kinds of atoms are constant in a given compound.
Thus when copper wire is cut into the smallest possible pieces, the atoms were intact as they are indivisible and all atoms have same mass and chemical properties.Thus the wire is still copper and does not change by cutting it
