17. Brittleness- a mineral turns into powder. Malleability a mineral can be flattened by pounding with a hammer. Ductility- A mineral can be stretched into wire. Flexible but inelastic-Minerals are bent but they remain in the new position. Flexible and elastic- Minerals are bent, and they bring back to their original position. Sectility - ability of minerals to be sliced by a knife. 17
