Detailed Explanation:

Noble metals (gold, silver, platinum, and platinum-group metals) are chemically inert, resist corrosion, and are typically found in pure native form in nature due to their nonreactive properties.

• Statement 1 is Correct: Noble metals like gold and platinum occur naturally in uncombined, pure metallic state.
• Statement 2 is Incorrect: Uranium and lead are highly reactive metals that occur as ores (e.g., uraninite, galena), not as noble metals.
• Therefore, only Statement 1 is correct, making Option 4 the correct answer.
