For a neutral atom, the oxidation state is zero. However, when atoms lose or gain electrons to form ions, they acquire an oxidation state that corresponds to the number of electrons lost or gained.<\/li>\n\n\n\n<li><strong>Fe\u00b3\u207a Ion<\/strong>: The iron ion in question is <strong>Fe\u00b3\u207a<\/strong>, which indicates it has a <strong>+3 charge<\/strong>. This means that the iron atom has lost three electrons.<\/li>\n\n\n\n<li><strong>Electron Configuration<\/strong>: The electron configuration of a neutral iron atom (Fe) is: [Ar]3d64s2[Ar] 3d^6 4s^2[Ar]3d64s2 In the case of Fe\u00b3\u207a, three electrons are lost. These are typically removed first from the 4s orbital, followed by the 3d orbitals. This results in the electron configuration: [Ar]3d5[Ar] 3d^5[Ar]3d5 This shows that the iron atom has now lost three electrons and has a net positive charge of +3.<\/li>\n\n\n\n<li><strong>Why +3?<\/strong>: The iron atom starts with an atomic number of 26, meaning it has 26 electrons in its neutral state. By losing three electrons to form Fe\u00b3\u207a, the number of electrons is reduced to 23, which is why it carries a +3 charge.<\/li>\n\n\n\n<li><strong>General Rules<\/strong>: Iron can form ions with different oxidation states, commonly +2 and +3. The +3 state (Fe\u00b3\u207a) is more stable in certain compounds, such as iron(III) chloride (FeCl\u2083), where iron is in the +3 oxidation state.<\/li>\n<\/ol>\n\n\n\n<p>In conclusion, the oxidation state of iron in the <strong>Fe\u00b3\u207a<\/strong> ion is <strong>+3<\/strong>, reflecting the loss of three electrons from the neutral atom.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-353.jpeg\" alt=\"\" class=\"wp-image-42671\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-353.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-353-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-353-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-353-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The oxidation state of iron in iron(?) ion Fe3+ The Correct Answer and Explanation is: The oxidation state of iron in the iron(III) ion, Fe\u00b3\u207a, is +3.
