Answer:
1.Diamonds are no longer the world's hardest substance
“Whilst its cubic arrangement makes a diamond very hard, it is also somewhat brittle,” says Professor Phillips. “This is because there are weaknesses along the cubic planes. ... It is a slow process and the diamond glows red even with cooling fluid flowing over it.”
2.Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It's made by rolling large slabs of aluminum until they are less than 0.2 mm thick. It's used industrially for a variety of purposes, including packing, insulation and transportation.
Usage notes. "Poor metals" is not a rigorous term, but the grouping is generally taken to include aluminium, gallium, indium, thallium, tin, lead, bismuth, and polonium. Occasionally germanium and antimony are also included, although these are usually considered to be metalloids.
ANSWER: because Hardness is the ability of a material to resist plastic deformation. Atoms in diamond are held together by extremely strong covalent bonds, by making them extremely hard. Because of this, diamond has no way of absorbing energy that's why diamond is hard and brittle.
