When a charge is given to a metallic sphere it spreads in its entire surface area,and when a charge is given to an insulating sphere, it spreads over its entire volume.Why is it so?

Metallic spheres are made of materials that allow electricity to flow through them easily, while insulating spheres are made of materials that do not conduct electricity.
In metallic spheres, the charges are distributed evenly throughout the material, with the highest concentration of charges at the surface.
The even distribution of charges in a metallic sphere results in a uniform electric field around the sphere, with the electric field lines pointing away from the surface.
A conducting sphere can influence the distribution of charges in nearby objects through induction, where the charges in the conducting sphere repel or attract the nearby charges.
In an insulating sphere, the charges are not free to move and are instead bound to the atoms in the material. This results in a non-uniform distribution of charges and a weaker electric field compared to a metallic sphere.
