The concept can be extended to solvated ions in liquid solutions taking into consideration the solvation shell. Iron is a metal in group VIII of the periodic table with atomic number 26 an atomic weight of 5585 and a density of 786. Click hereto get an answer to your question The effective radius of iron atom is 2 A.
All measurements given are in picometers pm. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. The Van der Waals radius r w of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom.
For uranium atom the Van der Waals radius is about 186 pm 186 10 10 m. It has a melting point of 1539 C. The iron atom which is given the symbol Fe has an atomic weight of 56 which compares with aluminium Al at 27 lead Pb at 207 and carbon C at 12In iron at room temperature the atoms are arranged in a regular pattern or lattice which is called body centred cubic or bcc for short.
