Extensive properties have to do with the amount or size of a substance. Gold and copper samples can be made to have the same mass or the same volume, or the same number of moles, or atoms.
Samples of platinum and copper can have the same extensive properties but not the same intensive properties for a couple of reasons. These are both metals but have differing numbers of electrons.
No. A "broken" atom of gold may be an ion, but it does not have the same chemical properties as an intact atom of gold.
Really none. That is why gold is so valuable. While other metals have similar properties to gold, none of them have the exact same. The closest metals to gold in terms of its properties are silver, platinum and palladium.

Intensive properties remain the same with a change in the amount of a substance - for example: temperature and density Extensive properties do not remain the same with a change in the amount of a substance - for example: mass and volume

Intensive properties depend only on the type of matter you're dealing with. For example, density: a single atom of gold will have the same density as a huge bar of gold, it doesn't matter how much of it there is. Extensive properties do depend on how much of the substance you have. A cubic centimeter of gold has more volume and mass than an atom of gold, so they are both extensive properties.
They do not have the same set of physical properties. At the very least they have different melting and boiling points, and different densities, and their colors are not identical.
Copper is an element that is in the same family as gold and silver. All of these metals are in the same group on the periodic table. Because of their similarities in structure, these metals have similar properties

no, gold is denser.
Density is an intensive property because it does not depend on the amount of matter present. If you have 2 grams of copper and 2000 grams of copper, they are going to have the same density. This cannot be said for extensive properties such as volume: 2 grams of copper will not have the same volume as 2000 grams of copper.See related questions below for more information.

Even though gold and copper are in the same family, copper is much more reactive than gold. This is why Copper rusts more than gold, and why there are so many copper compounds (IE copper silicate...). Copper is higher in the family, giving it these characteristics.
