An element is a substance that cannot be broken down into simpler substances. An atom is a single piece of an element. If you break an atom apart, you no longer have that substance.
its ion and atom properties differences is atom is like science ion-chemistry
Almost all the chemical properties of an atom are determined by the valence shell electrons or in general, by the no of electrons present in the atom. Since in an isotope and a general atom, no. of electrons is same, therefore they have similar chemical properties. Isotopes differ in atomic mass only and that is due to extra neutrons.
An atom.
An atom of calcium
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.
If it cannot be broken down and has the same properties, it is an element.
They are exactly the same. An atom of any element, not matter what substance it is a part of retains the same chemical properties. In other words, it has the same number of protons and electrons as well as the same electron configuration.

If a single atom of a hunk of matter is still the same substance as the matter, then that matter is an element. (Gold, sodium, carbon, uranium, and so forth) If the matter can only be broken down to a molecule, but not an atom, then it is not an element. (Salt, ammonia, sugar, alcohol, and so forth)
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.

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.
No. An atom is the basic unit of an element that retains all the properties of that element. So two elements can not have the same atom.

An atom of that element has all the properties of that element.
