    The statement, a hard material is easily scratched, is false, the answer is letter F. Harder materials have strong bonding between their neighboring atoms and it takes a greater amount of energy for them to break apart, even a scratch. The relative hardness of a mineral can be tested by the Moh’s scale or the mineral hardness. The Moh’s scale can be characterized by the ability of the mineral to resist scratch resistance by scratching a harder or softer mineral. It has a scale of 1 to 10 where 1 being the softest and 10 being the hardest.
