WebMay 16, 2024 · All metals can corrode. Some, like pure iron, corrode quickly. Stainless steel, however, which combines iron and other alloys, is slower to corrode and is therefore used more frequently. All small group of metals, called the Noble Metals, are much less reactive than others. As a result, they corrode rarely. WebSep 7, 2024 · The strong attraction between atoms in metallic bonds makes metals strong and gives them high density, high melting point, high boiling point, and low volatility. There are exceptions. For example, mercury is a liquid under ordinary conditions and has a high vapor pressure.
