Yes, if by "mix" you mean react chemically to form bonds with another element/comopound. All organic compounds have at least one carbon atom present: hydrocarbons, carbohydrates, carbon dioxide, proteins... the list is long.
because it has 4 outer electron which can connect with other molecules and gasses
For example halogens, carbon, oxygen, sulfur, other nonmetals.
carbon and any other atom
gold is a stable element,which means it does not readily combine with other elements
It is non-reactive because it's shells are full. Argon has three electron shells. It's third shell is filled with eight electrons. That is why it does not easily combine with other elements.
Elements have a number of electrons in their outer shell of the atom, all elements want to have a full shell and usually form with other atoms to do so. However, Xenon is a noble gas and already has a full outer shell and so does not combine with other elements unless it is made to do so.
No. Halogens combine readily with sodium
both other elements and carbon
For example halogens, carbon, oxygen, sulfur, other nonmetals.
carbon and any other atom
Helium does not combine with other elements and pure helium will not have carbon dioxide in it.

The chemistry of francium is not known but francium is considered the most reactive metal.
It is non-reactive because it's shells are full. Argon has three electron shells. It's third shell is filled with eight electrons. That is why it does not easily combine with other elements.
Usually Hydrogen and Oxygen but also with other elements to a lesser extent.
No. On their own they are elements. Carbohydrates do consist of carbon hydrogen and oxygen, but these elements can combine to make other compounds as well.

Diamond is a compound of carbon and does not combine, except minutely with other elements. Other elements can give diamond a subtle colour.
