This metal is iron.
Fe. Which is iron. rusting is oxidisation, and the iron turns to iron oxide (Fe2O3)
If i remember rightly, rust is just a metal oxide. So on a coin it would be copper reacting with the air, albeit slowly, forming copper oxide.
Yes - the steel under the rust is a metal (steel is iron with a trace of the non-metal, carbon), while the rust is iron oxide.
Because it rusts very easily. You woudn't want to use rusty water, believe me.
If they have iron oxide on them.
roadways are wet , salt is used on roads to melt ice and it corrodes steel .
most common metals tarnish slowly in exposure to air. metals that tarnish quickly in exposure to air are for example: lithium, sodium and potassium Gold is one of the slowest to tarnish.
The metal is getting rusty!
Iron needs oxygen and water to rust. When iron is exposed to air and moisture, a chemical reaction occurs, forming iron oxide (rust) on the surface of the metal. This process is accelerated in the presence of salt or acids.
