Noble metals – these are metals that are not subject to oxidation, corrosion and do not react with hydrochloric acid. In this they differ from most other metals (non-precious).
Due to their rarity, noble metals are expensive, which is why they are often called precious.
The table below provides a list of noble metals, including their names ( and Latin), symbol/designation, and basic chemical properties (atomic number, atomic/mass mass, density, melting and boiling points).
