      Hi there! ๐Ÿ‘‹

      โŒ No, a nail cannot rust in a vacuum.

      ๐Ÿงช Why?
      Rusting is a chemical reaction that happens when:

      Iron (in the nail)

      Water (or moisture)

      Oxygen (from the air)
      …are all present.

      ๐Ÿงฐ But in a Vacuum:
      There is no air โ†’ โŒ no oxygen

      There is no moisture โ†’ โŒ no water vapor
      ๐Ÿ” Therefore, no rusting can occur.

      ๐Ÿง  Summary:
      A nail needs oxygen + water to rust. In a vacuum, these are missing, so the nail stays rust-free! โœ…๐Ÿ”ฉ
