Is silver unrustable

Yes, silver is considered unrustable because it does not rust like iron or steel, which form rust when exposed to moisture and oxygen. However, silver can tarnish, developing a black or dull coating due to the formation of silver sulfide when it reacts with sulfur compounds in the air. This tarnishing is different from rusting and can be removed with proper cleaning. Overall, while silver is resistant to rust, it does require maintenance to keep its shine.
