True
A measure of how easily a mineral can be scratched is it's hardness.
yes, though not easily. Moh's hardness scale is not very even- the difference between 5 and 6 is not that great and a sharp point of 5 can possibly scratch a rough surface of 6, the with damage to the 5. This is certainly true where a mineral is recorded as hardness 6, but has variable hardness, so the surface being scratched is actually lower than 6 - Disthene is a well-known example of a mineral with hardness that varies in different directions.
Yes, quite easily even. You can rub with pencil eraser, it will come of in few stokes.
7 Properties include: Hardness, luster, streak, cleavage, density, color, and fracture.
Copper has a low hardness and is easily malleable. The element copper contains copper - it is often used for electrical conductivity.

Well you see, it's pretty simple. If a fingernail has a hardness of 2.5, and the question is asking what mineral can easily be scratched by a fingernail. Well then it is Graphite. It has a less hardness than your fingernails.
Gypsum (number 2 on the Moh's Hardness Scale)
The answer is hardness. On Moh's Scale of Hardness, talc is the softest which is a 1. Diamond is a 10 which is the hardest
