Carbon
Compounds are composed from elements.
An atom. However it should be noted that generally the valence electrons in an atom take part in a chemical reaction.
Salts are chemical compounds not elements.
Particles
In scientific terms, an element is anything that can be found on the Periodic Table of Elements (PTE). It is a pure substance, not mixed with anything else. Compounds are a combination of 2 or more elements. They cannot be found on the PTE.
If there are two or more elements or compounds physically combined, then it can no longer be an element.
Helium is an element (abbreviated "He"). Elements are types of substance that, when combined, form compounds and chemicals.
Atoms of elements combine to form compounds. A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances.
Sodium can be combined with the majority of other elements to form compounds; another chemical element cannot be obtained by chemical reactions.
no, but compounds are made of elements chemically combined.
ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
Compounds are formed from chemical elements.

Gold is not so reactive but has compounds with other elements.
