All elements have both chemical and physical properties. The question as asked has no meaning.
different chemical and physical properties
No, carbon cannot be separated into its parts by either chemical or physical process (unless you consider particle bombardment to be a physical process) which is why carbon is classified as an element.
a pure substance. :)
Chemical and physical changes depends on the chemical compostion.
physical
If something is not a mixture then it is a pure substance, either an element or a compound.

No, it is a pure substance. A "pure substance" does not mean an element. Rather, it means that the given substance has definite physical and chemical properties. "Pure substances" can be either "Elements" or "Compounds" because all substances belonging to these categories have definite physical and chemical properties.A mixture does not have definite physical and chemical properties, and combine in varying proportions.
Probably either copper or iron.
Chemical
I'm sorry but, there is no Element with either an Atomic Number or an Atomic Weight of 502.
