As far as I know the natural occurring elements begin at Hydrogen(H)-1 to Uranium(U)92. Minus Technetium(Tc)-43, Promethium(Pm)-61,Astatine(At)-85 and Francium(Fr)87 which were synthesized, but all other elements in between.

Elements that occur naturally as elements (rather than compounds) are: nitrogen (in air) oxygen (in air) gold silver copper
The weighted average of all of the natural occuring isotopes for a particular element is called its Atomic Weight (or Relative Atomic Mass)
They are elements. However, pure iron, gold and copper are produced from naturally occuring ores. In that respect, they are produced.
Now all the metals up to atomic number 94 (inclusive) are considered as natural chemical elements. It is difficult to post here a very long list; see the periodic table at the link below.
there are 51 natural elements we know of
the short definiton for mineral is: a mineral is a naturaly occuring inorganic solod formed from elements or coumpaonds
92 are natural occuring, other remaining are man made.
Technetium is an artificial chemical element.
The planet Earth and everything on it, including us, is composed of the chemical elements. Not only are elements found on Earth, but everything found on Earth is made of elements.
natural process means which is occuring by nature. for example- evaporation
Silver is a naturally occuring metal in nature.
No, trace elements are not necessarily radioactive. A link to a list of elements that have no natural radioactive isotopes is at a related question, below.
Gold-198 is not naturally occuring.
Today all elements up to atomic number 98 (including Cf) are considered as natural chemical elements.
Chemistry is the basic science that gives us a broad scope in which we can understand natural phenomena. Physics is more specific in its breadth because it examines the forces of natural phenomena. To elaborate chemistry studies revolve around the natural occuring elements and physics investigates the interaction involving matter.

Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
