Brief Summary

Iron is a Transition Metal with the symbol 'Fe' and contains 26 Protons & Electrons with 30 neutrons in the nucleus of the atom. Iron has an atomic mass of 55.845 g/mol and, at a temperature of 20°C, has a density of 7.87 g/cm³. It will melt at a temperature of 1535°C and boil at 2750°C.

Iron has been known since prehistoric times and is named 'Iron' Latin word "ferrum" meaning "iron".

Some common usages for Iron: steel and hemoglobin in blood that carries oxygen.

Definitions and Notes

Density listed is at a temperature of 20°C.

Isotopes are forms of an element who have the same atomic number but different mass because they contain different number of neutrons.

Half-life is the time required for a quantity of a subject to fall to half of its current quantity.
