Question 7. By using ThoughtCo, you accept our, Native Elements That Are Metalloids or Semimetals, Chemical Element Pictures - Photo Gallery, The Properties and Applications of Platinum. Most of the metals, however are found in the combined form as minerals. Native elements are chemical elements that occur in nature in an uncombined or pure form. The noble gases include helium, neon, argon, krypton, xenon, and radon. The gold group and platinum group, for example, are all elements that exist in the native state. What is the definition of native metal? Origin. Mining process. Assertion: Elements Pt, Ag, noble gases, etc. Native metal is a term used to describe metals discovered in their natural, elemental form – either as an alloy, or in pure form.
