Smartphones contain about 70 of the elements.

At the heart of chemistry is the periodic table. This visual representation of elements found in our ecosystem gives us insight into just how much science goes into building a high-quality smartphone. In this table, there are 83 non-radioactive elements. Of these, at least 70 can be found in smartphones. This means that 84% of stable elements found on the earth are contained within your cell phone! A large percentage of elements contained in a smartphone is metals.
