Copper, Silver, and Gold occur as elements instead of compounds.

Compounds are formed from elements.
True. Compounds do not have the same properties as the elements that form them.
both :P the elements and compounds in the original substances will join together to form a new substance, with possible elements left over i.e. oxygen+glucose --> carbon dioxide+water (respiration)
Some familiar compound elements include water (H2O), carbon dioxide (CO2), and sodium chloride (NaCl). These compounds consist of two or more different elements bonded together chemically.
Copper, Silver, and Gold occur as elements instead of compounds.
There are NO compounds in the Periodic Table. They are all Elements.
Copper, Silver, and Gold occur as elements instead of compounds.
yes
Copper, Silver, and Gold occur as elements instead of compounds.

Chemical compounds are formed from chemical elements.
All organic compounds contain carbon and hydrogen as a minimum. Other elements are found in some organic compounds such as oxygen, nitrogen or sulphur.
Some gasses are elements, such as oxygen and nitrogen. Some gasses are compounds of multiple elements put together, such as carbon dioxide.
Because the elements can combine in many ways to form compounds, and compounds can be mixed in many differed ways. Moreover, some elements occur in different forms. The elements carbon and hydrogen alone combine for form thousands of compounds.
