A gold ball has a high density. Gold is a dense material, which means that a small volume of gold has a high amount of mass packed into it.
High density materials have tightly packed particles, resulting in greater mass per unit volume (e.g. lead, gold). Low density materials have more spaced-out particles, leading to lower mass per unit volume (e.g. styrofoam, cork).
Charcoal has a low density because it is porous and lightweight.

Quite low density: 0.968 g·cm−3

Diffusion.
Gasses have an incredibly low density, less than a liquid or a solid.
High volume and low mass result in low density because density is calculated by dividing mass by volume. When the mass is low compared to the volume, the density will also be low because there is less mass per unit of volume.
