- Iron metal is a silvery, lustrous metal that has important magnetic properties.
- Iron ranks second in abundance among the metals and fourth in abundance among the elements.
- The earth’s core is largely metallic iron, but in the crust the element has had an opportunity to react with other substances and the free metal is rarely found except in meteorites or disseminated as minute specula in basaltic rocks.
