Lesson 24 - Rusting occurs when iron is exposed to oxygen. Rusting is a chemical reaction with reactants and products.

Lesson **metals - a group of elements that are usually hard solids and that have common characteristics: shiny, good conductivity, and malleability **corrosion - a chemical reaction, usually between a metal and the air (ex. - rusting) 153. **density - the mass of a known volume of a subtance; measured in g/cm3. (m/v)
