Chemically, the most common oxidation states of iron are iron (ii) and iron (iii) Iron shares many properties with other transition metals, including the other group 8 elements, ruthenium and osmium Iron forms compounds in a wide range of oxidation states, −4 to +7. Iron is a chemical element of the periodic table with chemical symbol fe and atomic number 26 with an atomic weight of 55.8452 u and is classed as transition metal and is part of group 8 (iron group) Iron is solid at room temperature. Iron’s electron configuration is [ar] 3d6 4s2, and thus it has 2 valence electrons
It is a very stable element Iron’s electronegativity is 1.83 on the pauling scale The element iron is an essential mineral for all living organisms. Iron is a relatively abundant element in the universe It is found in the sun and many types of stars in considerable quantity Its nuclei are very stable
Physical and chemical properties of iron General data, thermal properties, ionization energies, isotopes, reduction potentials, abundance of elements, crystallographic data. Iron comes from latin word ferrum It is reactive element, becomes rusty when exposed to damp air This process is known as corrosion There are four naturally occurring isotopes of iron exist, fe, fe, fe, and fe.
Iron atoms have 26 electrons and the shell structure is 2.8.14.2 The ground state electronic configuration of neutral iron is [ar] 4s2 and the term symbol of iron is 5d4 Description iron is a relatively abundant element in the universe Element properties, electonic configuration, isotopes, compounds, reactions and pictures.
