yes, element 26 (Fe)
Steel is not naturally occurring - it is an alloy made primarily of iron and carbon. Iron, the primary component of steel, is a naturally occurring element found in the Earth's crust. The process of making steel involves smelting iron ore and adding carbon to create the alloy.
Thallium is a naturally occurring element in the Earth's crust. It is not a man-made element.
Phosphorus is naturally occurring. It is found in rocks
No. Lithium is a naturally occurring element.
The lightest naturally occurring actinide on Earth is thorium, which has the atomic number 90. It is a naturally occurring radioactive element found in small amounts in soil and rocks.
No. Iron is a naturally occurring element.

Lead is an element---Go to http://en.wikipedia.org/ and look up lead---Natural or Synthetic is irrelevant when you're talking about elements. (If you don't know what I'm talking about, then maybe you ought to also read the wikipedia article on Chemical Element.)
Thallium is a naturally occurring element in the Earth's crust. It is not a man-made element.
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
Iron is an ore.
Uranium, number 92 is the last of the naturally occurring elements and, of course, it has 92 electrons.
We look to the naturally occurring element uranium as a nuclear fuel.
As a naturally occurring metallic mineral it is rare. As an element or component in the chemical composition of rocks and minerals, extremely common.
Naturally occuring.
Aluminum is an naturally occurring element
