Answer:

Two only......

Explanation:

Both platinum and gold are so-called Noble metals, and can still be found as nuggets in the Earth's crust. The occurrence of gold in alluvial deposits was responsible for several historical gold rushes in Australia, and the Americas.

Sodium, aluminum, and magnesium are FAR more reactive, and while their occurrence in ores and minerals would be far more common than the Noble metals, they would not be found in their elemental state.
