Detailed Solution

The above statement is true.
Gold (Au) and silver (Ag) are extremely non-reactive metals. As a result, they exist in their natural state and do not react with oxygen or any other element in the atmosphere. This is because noble metals such as platinum, gold, and silver do not easily mix with impurities such as silica, potassium, and so on. Even if they do mix, they can be easily separated by adding an acid. As a result, these metals exist in their natural state.
