Because in a conductor charges are free to move and since like charges repel each other they move as far as they can from each other, which is the surface.
Because like charges repel.
No, the charge held by a solid metal sphere and a hollow sphere of the same diameter would be the same. In both cases, the charge resides on the outer surface of the sphere due to the principle of electrostatic equilibrium.
If the sphere is conducting, all the charge is distributed uniformly on the outer surface of the sphere.
As of today no, but maybe in the future.
The curved outer surface of a circle is the perimeter.
The outer surface of the bone is called the periosteum.
