About Iron

Molecular Structure

Iron has the chemical symbol Fe.
Iron atoms join together in large numbers to form a giant metal molecule.

Atomic Structure

Iron as 26 protons and 30 neutrons in its nucleus giving it an Atomic Number of 26 and an atomic mass of 56.
Iron is in Period 4 of the Periodic Table because it has 4 electron shells.

Properties

Iron is a metal element so it is a good thermal conductor and a good electrical conductor.
Iron is a shiny solid at room temperature.
Iron is malleable.
Iron is sonorous.
Iron is ductile.
Iron is magnetic.
