River-worn lumps of gold are typically called nuggets. They can take a variety of shapes, from very flat to nearly spherical, and can be almost purely gold or contain pieces of the host rock, which is usually white quartz. Nuggets are generally worth more than spot price, but they're not as highly valued as crystalline gold or gold wire.

A lump of gold the size of a matchbox can be flattened to a sheet about the size of a tennis court due to gold's malleability.
Well, isn't that just a happy little question? If we know the mass of the second lump of gold is 96.5 g, and we know the density of gold is about 19.3 g/cm³, we can use a little math magic to find its volume. By dividing the mass of the second lump by the density of gold, we find that the volume of the second lump of gold is approximately 5 cm³. Just like that, we've painted a clear picture of the volume of our second golden friend.

Here in Alaska, we call them nuggets.

No - there are no cells in a lump of gold for example.
It is a group of precious minerals with Gold dominating, but other minerals like copper, Patina,silver and cadmium are known to be common in Gold Nuggets. This gives each gold piece a uniqueness. They are found in different colors like greenish, red, yellow, white and even blue.
The buoyant force on the lump of gold is less than its weight. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the submerged object. Since gold is denser than most fluids, the weight of the gold will exceed the weight of the fluid it displaces, resulting in a buoyant force that is less than the weight of the gold itself.
Gold nuggets are irregularly shaped pieces of gold that are found in nature. They are often small, solid lumps of gold that resemble the shape of chicken nuggets. The term "nugget" is believed to have originated from the Cornish word "nugg" which means "lump" or "chunk."
Depends how big the lump of 'gold' is. Probably it's worth a small amount to be melted down, but the buyer would have to take the risk that its value was small.
Depends a bit on what has been cast. A lump of gold or iron is an ingot, but if cast into a specific shape (like a model car) it would be a casting (not usually gold though!)
